Radiation effects on silica-based preforms and optical fibers-I: Experimental study with canonical samples

2008

International audience; Prototype samples of preforms and associated fibers have been designed and fabricated through MCVD process to investigate the role of fluorine (F) and germanium (Ge) doping elements on the radiation sensitivity of silica-based glasses. We characterized the behaviors of these canonical samples before, during and after 10 keV X-ray irradiation through several spectroscopic techniques, to obtain global information (in situ absorption measurements, electron paramagnetic resonance) or spatially-resolved information (confocal microscopy, absorption and luminescence on preform). These tests showed that, for the Ge-doped fiber and in the 300–900 nm range, the radiation-induc…

Laser resonance ionization scheme development for tellurium and germanium at the dual Ti:Sa–Dye ISOLDE RILIS

2016

Abstract The resonance ionization laser ion source (RILIS) is the principal ion source of the ISOLDE radioactive beam facility based at CERN. Using the method of in-source laser resonance ionization spectroscopy, a transition to a new autoionizing state of tellurium was discovered and applied as part of a three-step, three-resonance, photo-ionization scheme. In a second study, a three-step, two-resonance, photo-ionization scheme for germanium was developed and the ionization efficiency was measured at ISOLDE. This work increases the range of ISOLDE RILIS ionized beams to 31 elements. Details of the spectroscopy studies are described and the new ionization schemes are summarized.

Evidence for violation of the Gallagher-Moszkowski rules in154Pm

1972

The existence of two radioactive species of154Pm (1.8 min ground state and 2.65 min isomer) is established. The Nilsson model configurations assigned to these states give evidence against the validity of the Gallagher-Moszkowski coupling rules in154Pm.

Note on the decay of200Au

1972

Gamma and beta rays from the decay of200Au (48.4 min) were studied employing Ge(Li) and plastic detectors in various singles and coincidence arrangements. The intensity of the β-branch to the ground state of200Hg was determined as 79%, and the disintegration energy of200Au to be asQβ=2.26 ± 0.06 MeV. A tentative spin and parity assignment of (1,2)+ is proposed for levels at 1515.2 and 1972.5 keV in 200Hg

Independent and cumulative yields of very neutron-rich nuclei in 20 MeVp- and 18–41 MeVd-induced fission ofU238

1991

Independent and cumulative yields in nearly symmetric fission have been measured for the first time by bombarding $^{238}\mathrm{U}$ with 20-MeV protons and with 18-, 25-, and 41-MeV deuterons. Isobaric charge dispersion has been determined in the A=110, A=112, and A=114 mass chains and, from asymmetric fission, in the A=80 mass chain. The average isobaric charges in the p+U reaction were 44.01\ifmmode\pm\else\textpm\fi{}0.20 (A=110), 45.15\ifmmode\pm\else\textpm\fi{}0.15 (A=112), and 45.74\ifmmode\pm\else\textpm\fi{}0.15 (A=114). The widths (standard deviations) of the charge dispersion curves were 0.82\ifmmode\pm\else\textpm\fi{}0.08 (A=112) and 0.54\ifmmode\pm\else\textpm\fi{}0.08 (A=114…

‘Old English lida and the Sailors of the North Sea’

2017

The essay examines the words for ‘sailor’ in the Germanic languages, with particular regard to those going under the sobriquet of North Sea Germanic languages. The research begins with the lida of Maxims I and his safe return home. As with OE lida and līðend, nomina agentis from verbs of motion turn out to be among the most frequent formations for ‘sailor’, both in OE and many other Germanic languages. The research does not yield a common stock of Germanic words, but for the cognates of OE scipmann and sǣmann, that, however, are not recorded in all the Germanic languages. As to the līðend-compounds, their occurrence in more than one language might be due to the influence of OE models on bot…

Glimpses of the Hereafter in the Late-Medieval Thet Freske Riim

2014

The article analyzes a passage of the narrative poem Thet Freske Riim, one of the few non-legal texts preserved in Old Frisian. The passage in question is a digression describing the Joys of Heaven and the Horrors of Hell, which so far has attracted little attention in the scholarly literature on medieval accounts of the hereafter. The representations of the afterlife and its realms circulating in Medieval Europe draw inspiration from a wide body of both orthodox and apocryphal literature on ecstatic dreams, of which one of the most influential work is the Visio Sancti Pauli or Apocalypse of Paul. The study aims to identify – in the examined passage – themes and features of otherworldly lit…
