Abstract 

A shell-model description for intruder states in both odd-mass and odd-odd nuclei is given starting from 1p1h excitations across closed shells. Combining these results with the behaviour of 0+ intruder states in even-even nuclei, evidence for a scaling of the energy with the number of particle and hole pairs formed in exciting the intruder configuration is obtained.
