p-shell nuclei in a (0+2)

An empirical effective interaction for the {ital A}=4--16 {ital p}-shell nuclei in the complete (0+2){h bar}{omega} model space is presented, which also reproduces the predominant 2{h bar}{omega} intruder states. The results are not spoiled by the mixing catastrophe. The inclusion of 2{h bar}{omega} 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.
