Isomeric Cross-Section Ratios for 93,95Tc and 95Nb Nuclei

Section: Nuclei and Nuclear Reactions
Original Author's Text: Ukrainian

Abstract: Isomeric cross-section ratios have been measured for 93,95Tcm,g nuclei in the (d, n) and (p, γ) reactions, for 93,95Tcm,g nuclei in the (d, n) reaction, and for 93,95Tcm,g nuclei in the (d, α) reaction for deuterons and protons with maximum energies of about 4.5 and 6.8 MeV, respectively. Experimental values of isomeric cross-section ratios are compared with theoretical values calculated using the codes TALYS-1.4 and EMPIRE-3.2. A high influence of non-statistical effects is observed.

Key words: Isomeric ratio, activation method, γ-spectroscopy, statistical model.
