摘要: Abstract 92, 94Nb and 94, 96, 98Tc have been produced by the (p, n) reaction at proton energies on near d 5 2 isobaric analog resonance. 95,97Tc γ) below threshold. Internal conversion electrons due to decay of their excited states were detected on-line with a mini-orange spectrometer which is optimized for energy range 50 500 keV. Gamma rays from these nuclei thin Ge(Li) detector. Isomeric-delayed internal γ-rays observed, using nanosecond-pulsed beam. The coefficients 55 transitions in determined multipolarities deduced. multipolarity predominantly M1. Negative parities assigned through use resonance enhancements population negative-parity final states. systematic behavior 2−, 3− doublet g 9 ⊗ multiplet discussed.
