Introduction {#intro}
============

Our understanding of the structure of the atomic nucleus is mainly based on studies of stable nuclei or nuclei close to stability. However, it is now well established that the nuclear structure changes with the addition of the isospin degree of freedom, i.e. when studying nuclei far away from the valley of stability. The study of these exotic nuclei is today a well established tool for a deeper understanding of nuclear structure.

The exotic odd-odd nucleus $^{22}Al$ (Z=13, N=9) is situated at the proton drip line of the nuclear chart and is evaluated to be bound by only 20 keV [@audi03]. It was observed
