Prompt and delayed spectroscopy of 203At : Observation of a shears band and a 29/2+ isomeric state

2018

Using fusion-evaporation reactions, a gas-filled recoil separator, recoil-gating technique and recoil-isomer decay tagging technique we have extended the level scheme of 203 At ( N = 118 ) significantly. We have observed an isomeric [ τ = 14.1 ( 3 ) μ s ] state with a spin and parity of 29 / 2 + . The isomeric state is suggested to originate from the π ( h 9 / 2 ) ⊗ ∣ ∣ 202 Po ; 11 − ⟩ coupling, and it is depopulated through 286 keV E 2 and 366 keV E 3 transitions. In addition, we have observed a cascade of magnetic-dipole transitions which is suggested to be generated by the shears mechanism. peerReviewed

Decay studies of the long-lived states in Tl186

2020

Decay spectroscopy of the long-lived states in 186Tl has been performed at the ISOLDE Decay Station at ISOLDE, CERN. The α decay from the low-spin (2−) state in 186Tl was observed for the first time and a half-life of 3.4+0.5−0.4 s was determined. Based on the α-decay energy, the relative positions of the long-lived states were fixed, with the (2−) state as the ground state, the 7(+) state at 77(56) keV, and the 10(−) state at 451(56) keV. The level scheme of the internal decay of the 186Tl(10(−)) state [T1/2=3.40(9) s], which was known to decay solely through emission of 374-keV γ-ray transition, was extended and a lower limit for the β-decay branching bβ>5.9(3)% was determined. The extrac…

Level structure above the 17+ isomeric state in 152 69 Tm83

2018

Excited states above the 17+ isomeric state in the proton-rich nucleus 152Tm were established by employing the recoil-isomer tagging technique. Data were collected using the JUROGAM gamma-ray array and the GREAT spectrometer together with the recoil ion transport unit (RITU) gas-filled recoil separator and analyzed to identify the prompt and delayed γ decays from the levels in 152Tm. Shell-model calculations, either in a large valence space or in a reduced model space with five protons in the π0h11/2 orbital and one neutron in the ν1f7/2 orbital, agree with the observed energies of the yrast levels up to angular momentum J = 21. The observation of near degeneracies in the energy spectrum ca…

Lifetime Measurements of Excited States in $^{172}$Pt and the Variation of Quadrupole Transition Strength with Angular Momentum

2018

Lifetimes of the first excited 2 + and 4 + states in the extremely neutron-deficient nuclide 172 Pt have been measured for the first time using the recoil-distance Doppler shift and recoil-decay tagging techniques. An unusually low value of the ratio B ( E 2 : 4 + 1 → 2 + 1 ) / B ( E 2 : 2 + 1 → 0 + gs ) = 0.55 ( 19 ) was found, similar to a handful of other such anomalous cases observed in the entire Segré chart. The observation adds to a cluster of a few extremely neutron-deficient nuclides of the heavy transition metals with neutron numbers N ≈ 90 – 94 featuring the effect. No theoretical model calculations reported to date have been able to explain the anomalously low B ( E 2 : 4 + 1 → …

Children’s Emotions in Educational Settings: Teacher Perceptions from Australia, China, Finland, Japan and Spain

2019

The transition to formal education is a critical transition in children’s lives that has importance for socio-emotional and behavioral functioning. In the transition process, teachers are key players who work intensively with children and their families. This article focuses on teachers’ perceptions of children´s socio-emotional behavior during the transition from preschool to primary school. We collected qualitative teacher interviews from 112 teachers from five different countries—Australia, China, Finland, Japan and Spain. The research questions were: (1) How do teachers in the five countries perceive children’s abilities in expressing and regulating emotions. (2) How are children’s emot…

The Work of Cultural Transition: An Emerging Model

2016

In today’s uncertain, fluid job market, transnational mobility has intensified. Though the concept of cultural transition is increasingly used in sport and career research, insight into the processes of how individuals produce their own development through work and relationships in shifting cultural patterns of meaning remains limited. The transnational industry of sports, in which athletes’ psychological adjustment to cultural transitions has implications for both performance and meaningful life, serves as a backdrop for this article. This study applied the life story method to interviews with 15 professional and semi-professional athletes, focusing particularly on the cultural transition …

Patterns and Predictors of Recovery from Poor Health Status Measured with the Chronic Obstructive Pulmonary Disease (COPD) Assessment Test in Patient…

2019

Recent recommendations for chronic obstructive pulmonary disease (COPD) suggest that evaluation and management should focus on patient health status. Despite the frequency of poor health status and its negative impact on patients with COPD, little is known about how poor or non-poor health status persists and/or remits over time or what factors might predict recovery from a poor health status. The aim was to determine the likelihood of transitioning between poor and non-poor health status in patients with stable COPD followed for 2 years and to investigate factors that might predict recovery from poor health status. We prospectively included 137 patients with stable COPD (mean age, 66.9 yea…

Transitions between care settings after enrollment in a palliative care service in Italy: a retrospective analysis.

2013

This study was a retrospective analysis of prospectively collected data that aimed to map patients’ care transitions following admission to a specialist palliative care service in Italy called Antea Centre. Patients’ data was extracted from the Antea local database from 2007 to 2011. External transitions were defined as a change in the setting of care, with the patient no longer being cared for by Antea staff. Internal transitions were defined as a change in the setting of care, with the care still being provided by Antea staff. A total of 1123 patients out of 5313 admitted to the palliative service (21%) experienced transitions. Patients who experienced no transitions after their admissio…

Educational attainment and permanence in NEET situation among youth

2018

Using the French Labour Force Survey, this paper analyses the individual and institutional effects on the transitions into and out of NEET status before and after the crisis. In particular, we question whether the profiles or the labour market transition patterns of young people have changed since the economic crisis. The econometric results indicate that the NEET risks vary according to age, sex, educational level and social origins. They also show that the transition out of NEET status is more related to the educational attainment, after 2008. Conversely, the lack of human capital and social capital increases the retention of youth in NEET situations.
