Abstract

An intermediate coupling calculation has been carried out for nuclei of mass 18 and 19, taking full account of the configurational mixing of the 2 s and 1 d shells. The spin-orbit splitting of the d -level and the relative position of the s -level are taken from the observed 17 O spectrum, while the strength of the two-body central force is treated as a free parameter. No excitation of the 16 O closed shell core is considered. Excellent agreement is found for the positions of the even-parity energy levels and their properties, including the reaction data. The configurational mixing is very large, the strength of central force is similar to that required for the deuteron, and the mode of coupling is similar to that in the lithium nuclei.
