The lifetimes and energies associated with low-energy gamma transitions from the 93Nb(n,γ)94Nb, 107Ag(n,γ)108Ag, and 109Ag(n,γ)110Ag reactions have been studied using a high-resolution Ge(Li) X-ray spectrometer. New weak transitions are observed in the decay of 110Ag at 30.84, 38.19, 41.78, and 136.65 keV, while intense gamma transitions at 105.6, 235.8, and 266.95 keV are resolved into doublets. The half-life of the state involving the intense 117.47 keV transition in 110Ag and the 215 keV transition in 108Ag is confirmed as 36.5 ± 2.0 ns and 54 ± 8 ns, respectively, while a new delayed state associated with the gamma transition of 99.404 keV (T1/2 = 30 ± 5 ns) in 94Nb is observed for the first time. The upper limits for the half-lives involving most of the intense transitions in all the three isotopes are also reported. A level scheme is proposed and discussed for 108Ag.

Some of the low energy gamma transitions occurring in the decay of 97Zr to 97Nb were investigated with a 50 cm radius double focusing magnetic spectrometer. On the basis of the conversion coefficients determined from this investigation, a gamma–gamma directional correlation experiment was carried out for the 355–1750 keV cascade occurring in 97Nb. The combined results of the two investigations made it possible to assign spins and parities for a few levels in 97Nb for the first time.

Abstract The contents of selected elements (Mn, Fe, Co, Ni, Cu, Zn, Hg and Pb) in samples of loose tea of agrimony “Repikovy čaj” (Agrimonia eupatoria L.) were studied in this work. Identification and determination of the selected elements content were performed using X-ray fluorescence spectrometry - the nuclear analytical method based on the interaction between low-energy gamma and X radiation and analysed substance. Solid form samples were pressed in tablets and directly analysed. Prepared infusions were analysed after the preconcentration of the elements using precipitation with thioacetamide and ammonium diethyldithiocarbamate with subsequent filtration of created precipitates through a nitrocellulose filter. Detection limits obtained from both methods were compared and their suitability for elemental analysis of plant preparations was discussed.
