Several observables for the A=4–16 p-shell nuclei, resulting from a calculation in the complete (0+2)ħω model space, are presented. It is shown that the 2ħω admixtures are substantial. The calculated values of these observables are compared with the experimental data. Not only can the properties of many intruder states be reproduced correctly, but also the description of predominantly 0ħω states is often improved considerably.
