Abstract
An attempt has been made to understand the low-lying spectra of states in and , without having to introduce configurations with a very high number of holes. The analysis of includes 0p-0h, 2p-2h, and 4p-4h configurations, with the particles and holes restricted to the and orbitals, respectively. The effects of higher orbitals are simulated by lowering the single-particle splitting. The model reproduces all the known levels in with remarkable accuracy. The calculation in includes only the 2p-0h and 4p-2h configurations, and the same matrix elements used in the analysis of . Again all the known states are reproduced, including the group between 5.85 and 6.70 MeV. These states are predominantly of 4p-2h nature, with the four particles coupled to their maximum possible isospin.
