New Spins for ground states and isomers in Pd and Pd
Levels in 115Pd and 117Pd nuclei, populated in the spontaneous fission of 248Cm were studied by means of prompt gamma spectroscopy using the EUROGAM2 array of Anti-Compton spectrometers. Negative-parity, I = 9/2 excitations were identified, which are associated with the long-lived isomers in these nuclei, reported previously as 11/2- excitations. The new data indicate spin and parity 3/2 + for ground states in 115Pd and 117Pd instead of 5/2 + proposed in previous works. This result implicates changes of spin assignments to other levels in both nuclei
Discovery of the thallium, lead, bismuth, and polonium isotopes
Currently, forty-two thallium, forty-two lead, forty-one bismuth, and
forty-two polonium isotopes have so far been observed; the discovery of these
isotopes is discussed. For each isotope a brief summary of the first refereed
publication, including the production and identification method, is presented.Comment: to be published in At. Data Nucl. Data Table
Historical sketch of military thought on engagement of cyclists in the II Commonwealth Polish Army
The issue of functioning of cyclists in the military forces of the II Commonwealth has not been researched properly so far. This paper aims at presentation of
the development of military thought pertaining to their organization, shape and
tactic usage. At the beginning cyclists were hardly present in the Polish Army,
their small groups, used for small, specific tasks, did not have much tactical
impact. During the interwar period it was pondered how to form them into small
tactical units capable of fulfilling a wide range of tasks. Squadrons in cavalry
units and platoons in infantry proved to be a good solution. That is how they were
organized at the outbreak of World War II, in September 1939. The discussion
conducted in the years 1923–1939 in specialist press, presented in this article,
is not to be neglected as functioning of these units was not included in any military regulations or instructions. It was only in 1935 that the first works on the
preliminary instruction on their tactical usage appeared. Engagement of cyclists
for infantry, cavalry and armoured motorized weapons was pondered then.918720

Production and identification of new, neutron-rich nuclei in the {sup 208}Pb region
The recently developed methods allowing the experimental studies on new neutron-rich nuclei beyond doubly-magic {sup 208}Pb are briefly described. An identification of new neutron-rich isotopes {sup 215}Pb and {sup 217}Bi, and new decay properties of {sup 216}Bi studied by means of a pulsed release element selective technique at PS Booster-ISOLDE are reported
SI system - engineering against medicine
W artykule omówiono problem jednostek miar stosowanych w medycynie, ich zgodności z obowiązującym układem SI oraz jednostkami pozaukładowymi, dopuszczonymi przez stosowne rozporządzenia. Dokonano oceny poprawności jednostek miar stosowanych w medycynie w aspekcie zgodności z definicją pomiaru i jego cechami, jednoznaczności i wiarygodności. Podjęto próbę takiego przedstawienia niektórych jednostek, aby były one poprawne i zrozumiałe zarówno dla lekarzy, jak i dla inżynierów.Problems concerning units of measure used in medicine, their compatbility with the SI system and with unts do not belong to the SI system but are acceptable according to relevant decrees have been presented. The evaluation of correctness of units of measure used in medicine in the ligh of their consistence with the definition of measurement and its properties, explicitness and reliability has been carried out. An attempt to present some units n such a way that they are correct and clear forboth physicians and engineers has been undertaken
Trap-assisted studies of odd, neutron-rich isotopes from Tc to Pd
We review the present and future of trap-assisted structure studies of
odd, neutron-rich Tc, Ru, Rh and Pd isotopes at the limits of present experimental techniques. These nuclei of refractory elements are produced in light-particle
induced fission and filtered by their mass number with the IGISOL mass separator.
Further mass separation with the JYFLTRAP Penning trap system provides a clean,
monoisotopic beam perfectly suited for precise nuclear spectroscopy. Connecting the
IGISOL and the JYFLTRAP facilities to the recently installed MCC30/15 cyclotron
opens new prospects for post-trap spectroscopy of very exotic, neutron-rich nuclei.peerReviewe
