|Abstract:||The structure of excited states in Sn-132, fed in the β-decay of In-132, has been investigated. Absolute intensities were deduced from γ-singles measurements. From multi-spectrum analysis of γ-lines the half-life of In-132 was determined to be 186 ± 22 ms. A level scheme based on γγ and βγ coincidences is presented. The conversion electron spectrum has been studied and internal conversion coefficients deduced for two low-energy transitions. The total decay energy of In-132 was determined, from γ-gated β-spectra, to be Q(β) = 13.6 ± 0.4 MeV. A lower limit of 6.968 MeV for the neutron separation energy in Sn-132 was deduced from the β-delayed neutron spectrum. The experimental results on the level structure of the doubly closed shell nucleus Sn-132 show that the shell model is applicable even far from the valley of stability.|
