Journal ArticleDOI
Identification of short-lived isotopes of zirconium, niobium, molybdenum, and technetium in fission by rapid solvent extraction techniques
TL;DR: In this article, the Schicht wurde bei einem Potential von 0, 0 5 bis 0, 1 5 V in 0, 5 η Salzsäure (Zn, Tl) oder 0,5 η SALPERSÖURE (Co, Pb) von 70 °C gebracht, wägbare Mengen an radioaktiv markiertem Kobalt, Zink, Thallium oder Blei gemeinsam with Wismut aus komplexalkalisc
Journal ArticleDOI
Decay studies of neutron-rich products from 76Ge induced multinucleon transfer reactions including the new isotopes 62Mn, 63Fe and 71, 72, 73Cu
E. Runte,W. D. Schmidt-Ott,P. Tidemand-Petersson,R. Kirchner,O. Klepper,W. Kurcewicz,E. Roeckl,N. Kaffrell,P. Peuser,K. Rykaczewski,M. Bernas,Ph. Dessagne,M. Langevin +12 more
TL;DR: In this article, the half-life of 63 Fe was measured to be 4.9(5) s and the decays of 73 Zn and 74 Zn were obtained.
Journal ArticleDOI
Collective states fed by weak α-transltions in the 232U chain
TL;DR: In this paper, the decay of the 232 U decay chain was investigated down to 212 Pb using Ge(Li) spectrometers in single and coincidence measurements in terms of the Hindrance Factor (HF) calculated for all α-transitions.
Journal ArticleDOI
New neutron-deficient tellurium, iodine, and xenon isotopes produced by reactions of 290 MeV 58Ni ions on 58Ni and 63Cu targets
R. Kirchner,O. Klepper,Gunnar Nyman,W. Reisdorf,E. Roeckl,D. Schardt,N. Kaffrell,P. Peuser,K. Schneeweiss +8 more
TL;DR: The new neutron-deficient nuclei 108−110 Te, 110−114 I, and 114 Xe were produced as evaporation residues from reactions of 290 MeV 58 Ni ions on 58 Ni and 63 Cu targets and identified by mass separation and subsequent decay spectroscopy as discussed by the authors.
Journal ArticleDOI
Decay studies of neutron-rich isotopes of manganese, iron, cobalt, nickel, copper and zinc
E. Runte,K. L. Gippert,W. D. Schmidt-Ott,P. Tidemand-Petersson,L. Ziegeler,R. Kirchner,O. Klepper,P. O. Larsson,E. Roeckl,Dieter Schardt,N. Kaffrell,P. Peuser,M. Bernas,P. Dessagne,M. Langevin,K. Rykaczewski +15 more
TL;DR: In this article, a 46 mg/cm2 thick natW target was irradiated with an 11.5 MeV/u 82Se beam and the decay properties of the nuclei 61Mn, 63Fe, 63Co and 69Cu were measured for the first time.
