Configuration interaction and rotational structure in 8Be

A configuration interaction calculation for ⁸Be is carried out in which $\text{0}\text{h}\text{?}\text{ω, 2}\text{h}\text{?}\text{ω}$ and $\text{4}\text{h}\text{?}\text{ω}$ configurations are taken into account. The results indicate a reordering of levels into new rotational bands and a grouping of bands into “families”.
