${}^{10}$Be in the Cluster Shell Model

The Cluster Shell Model (CSM)describes light nuclei in terms of $k-\alpha$ particles and $x$ extra nucleons, in which the extra nucleon move in the deformed field generated by the geometric configuration of $\alpha$-particles. We present the first study for the case $x=2$ nucleons in application to ${}^{10}Be$ as a cluster of two $\alpha$-particles and two neutrons.
