Abstract
An empirical effective interaction for the A=4–16 p-shell nuclei in the complete (0+2)ħω model space is presented, which also reproduces the predominant 2ħω intruder states. The results are not spoiled by the mixing catastrophe. The inclusion of 2ħω states also leads to a new feature not encountered before in smaller model spaces, i.e., the appearance of radially excited states. The latter can be observed experimentally in certain cases.Keywords
