Low spin, negative parity states in the N = 103 isotones of 171Er, 173Yb and 175Hf identified by thermal neutron capture reactions

摘要: Abstract Energies and intensities of the γ-rays following thermal neutron capture in enriched samples 170 Er, 172 Yb 174 Hf have been measured using internal reactor targets a three-crystal Ge(Li) pair anti-Compton spectrometer. The reaction Q -values, excitation energies intensity values deduced. Decay schemes 171 173 175 are presented together with spins Nilsson assignments low-lying rotational bands populated from states.
