Spectroscopy of neutron-rich 34, 35, 36, 37, 38P populated in binary grazing reactions
The neutron-rich nuclei 34, 35, 36, 37, 38P were populated in binary grazing reactions initiated by a beam of 36S ions at 215 MeV incident on a thin 208Pb target. The combination of the PRISMA magnetic spectrometer and the CLARA array of escape-suppressed Ge detectors was used to detect gamma rays in coincidence with projectile-like nuclear species. Further evidence to support the observed gamma decay of excited states of the populated phosphorus isotopes is provided by gamma-gamma coincidence measurements based on the results of an earlier thick-target deep-inelastic experiment. Level schemes for 34, 35, 36, 37, 38P are presented and discussed within the context of state-of-the-art shell-model calculations. In particular, new spin and parity assignments are proposed for a number of excited states of 36P. The evolution with neutron number of the energy difference of the low-lying 3/2+ and 1/2+ states in the odd-A isotopes of phosphorus, and the relationship to nuclear collectivity, is discussed. The evolution with neutron number of the shell-model wave functions of the first 1/2+, 3/2+, and 5/2+ states of the odd-A phosphorus isotopes and of the first 3−, 4−, and 5− states of the even-A isotopes is also explored.
