The structure of 14N and 16O

Abstract

Using an empirical single-particle spectrum from 13C and the Cornell local density-dependent approximation to the nuclear reaction matrix, two-particle and four-particle model-space configuration-mixing calculations are carried out for 14N and 16O. Correlations are allowed for in the 12C core. The spectrum of 14N is reasonably well reproduced. If the d 3 2 state is excluded from the model space the structure of 16O is not well represented. However, there is a dramatic lowering of the energy of the rotational bands when the d 3 2 state is included and the spectrum of 16O is given extremely well without any free parameters.
