Nuclear Data Sheets A=32
Nuclear spectroscopic information for experimentally investigated nuclides of mass 32 (Ne, Na, Mg, Al, Si, P, S, Cl, Ar) has been evaluated. The principal sources of the Adopted Levels presented for nuclides close to the stability line are Endt's evaluations (1990En08, 1978En02). The data sets for reactions and decays, including all available gamma-ray data, are based mostly on the original literature. Except for the half-life of {sup 32}Ne decay, no other details about its decay characteristics are available. Structure data for {sup 32}Ne and {sup 32}Na are limited to only one excited state in each. The {sup 32}Mg nuclide is of central and prime relevance in the 'island of inversion' at or near N = 20 semi-closed shell. The lifetime of only one excited state in {sup 32}Mg is known. The spin-parity assignments of several levels in this nucleus are not quite firm. The structure of {sup 32}Ar is limited to only one known state at low energy and two resonances in the giant-dipole excitation region. The {sup 32}P, {sup 32}S and {sup 32}Cl remain the most extensively studied nuclei through various reaction channels.
