For $^{10}Be$ we should actually compare the theoretical models with the combined result (‘$T=1$’ + ‘$T=2$’).

These results indicate that the simple models are not too bad as a first orientation but there are fluctuations -sometimes the ratio is less than two, sometimes greater. We will discuss these matters in more detail in the context of the figures.

In Figs $1$ and $2$ we show the cumulative energy weighted strength distributions in $^8\mbox{Be}$ for the ($x,y$) interaction and for the Hamiltonian $H_{Q}$ i.e. the quadrupole-quadrupole interaction. The results for the two interactions are quite similar. The outstanding feature is that there are two rises separated by a rather wide plateau. For the ($x,y$) interaction the first rise is to a plateau at about $12$ $\mu_N^2MeV$ followed by a second rise to about $20.8$ $\mu_N^2MeV$. For the $Q \cdot Q$ interaction the first plateau is at $10.25$ $\mu_N^2MeV$ and the second at $14$ $\mu_N^2MeV$. A simple self-consistent Nilsson
