摘要: Abstract Low-energy gamma and conversion electron spectra following the 121Sb(n, γ)122Sb reaction in energy range 50–500 keV 16–500 respectively have been studied with bent crystal magnetic spectrometers. Gamma-gamma coincidences 60–550 investigated a Ge(Li)-Ge(Li) arrangement. Proton from 13 15 MeV deuteron-induced (d, p) reanalysed. The 122Sb level scheme involving 36 excited states 0–920 has constructed. Parity was determined for all levels introduced. Unique spin values are assigned to 31 levels. It is shown that present energies differ those previously found 123Sb(d, t)122Sb by systematic shift of 41 keV.
