Shell-model calculation of the even-parity states of Ca43

An attempt has been made to describe the even-parity states of Ca43 in terms of the spherical shell model, including all the shell-model states arising from the configuration [1f72]4[1d52-2s12-1d32]-1. This model gives a good account of the observed energy spectrum. The calculated spectrum of T=52 states is consistent with the level splitting in K43. However, these T=52 states are predicted to occur about 2.7 MeV too low in the Ca43 spectrum. The shell-model wave functions were used to calculate (p,d) and (d,p) spectroscopic factors, logft values, and M2 hindrance factors. In general, agreement with experiment is good, with the possible exception of the 32+→52-M2 hindrance factor.
