Precision mass measurements of 67Fe and 69,70Co: Nuclear structure toward N = 40 and impact on r-process reaction rates
2020
Accurate mass measurements of neutron-rich iron and cobalt isotopes 67Fe and 69,70Co have been realized with the JYFLTRAP double Penning-trap mass spectrometer. With novel ion-manipulation techniques, the masses of the 69,70Co ground states and the 1/2− isomer in 69Co have been extracted for the first time. The measurements remove ambiguities in the previous mass values and yield a smoother trend on the mass surface, extending it beyond N=40. The moderate N=40 subshell gap has been found to weaken below 68Ni, a region known for shape coexistence and increased collectivity. The excitation energy for the 1/2− intruder state in 69Co has been determined for the first time and is compared to lar…

We use the concept of 2-coloring in analyzing UH3 graphs and building exact specifications of functions to find new UH3 graphs by Hamiltonian cycle edge extractions
Review of Particle Physics
2020
The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 2,143 new measurements from 709 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. Particle properties and search limits are listed in Summary Tables. We give numerous tables, figures, formulae, and reviews of topics such as Higgs Boson Physics, Supersymmetry, Grand Unified Theories, Neutrino Mixing, Dark Energy, Dark Matter, Cosmology, Particle Detectors, Colliders, …
Exploring the boundaries of the nuclear landscape : α-decay properties of 211Pa
2020
Employing the recoil ion transport unit (RITU) and a fusion-evaporation reaction, the α decay of 211Pa has been identified via the implantation-decay correlation technique through observation of chains up to four consecutive decays. An α-particle energy and half-life of 8320(40) keV and 3.8+4.6−1.4 ms, respectively, were measured, corresponding to favored α decay. In addition, more precise α-decay properties of 212Pa and 213Pa were obtained due to accumulated statistics. The present data were compared to those predicted by selected atomic mass models and it was used to estimate the possibility of observing proton emission from these isotopes. peerReviewed
Liturgie anlässlich der Staatsund Nationalfeierlichkeiten in Polen Geschichte, Probleme und Herausforderungen
2018
Historia, problemy i wyzwania. Historia Polski od przyjęcia chrztu w 966 r. pokazuje, jak pewne wydarzenia społeczne łączono z celebracjami liturgii. W artykule została podjęta próba pokazania nie tylko historii tego zjawiska, ale też problemów, jakie się z nim wiązały. Łączenie wątków religijnych ze świętowaniem wydarzeń narodowych miało miejsce wtedy, gdy pojawiało się zagrożenie wewnętrzne lub zewnętrzne. Przykładem są tzw. śluby lwowskie króla Jana Kazimierza, który 1 kwietnia 1656 r. uroczystym aktem religijno-państwowym oddał Rzeczpospolitą pod opiekę Matki Bożej, którą ogłosił Patronką oraz Królową Królestwa Polskiego i wszystkich jego ludów. Fakt ten przyczynił się zdecydowanie do t…

Direct mass measurements on neutron-deficient xenon isotopes with the ISOLTRAP mass spectrometer
2002
The masses of Xe isotopes with 124 A 114 have been measured using the ISOLTRAP spectrometer at the on-line mass separator ISOLDE/CERN. A mass resolving power of 500000 was chosen resulting in an accuracy of m 12 keV for all isotopes investigated. Con icts with existing mass data of several standard deviations were found. peerReviewed
Insediamenti rurali a corte nella Sicilia occidentale : la tenuta dello Zucco di Henri d’Orléans, duca d’Aumale
2010
Lo studio indaga sulle trasformazioni del complesso rurale fortifi cato a corte chiusa della Tenuta dello Zucco, fl orida realtà agricola siciliana ottocentesca inserita, in Provincia di Palermo nel territorio di Carini, all’interno di un grande ex feudo. Il bene rurale, oggi in stato di parziale abbandono, conobbe, dalla metà dell’Ottocento, con l’intraprendenza imprenditoriale e la disponibilità fi nanziaria del proprietario Henri d’Orléans, duca d’Aumale, il suo massimo splendore architettonico e produttivo. Dopo una disamina morfo/tipologica sugli insediamenti rurali a corte della Sicilia occidentale, il volume ricostruisce, attraverso fonti bibliografi che, fotografi che, iconografi ch…
