values of $B(E2)$ for the lowest two $2^+$ $T=1$ states in $^{10}\mbox{Be}$, we get for the right hand side of the sum rule a value of $8.80$ $\mu_N^2MeV$. Again, as in the case of $^8\mbox{Be}$, this is larger than the value $7.03$ $\mu_N^2MeV$ that is obtained by using all $2^+$ $T=1$ and all $2^+$ $T=2$ states.

The corresponding numbers in small space for $^{10}\mbox{Be}$ are:

= 1. Energy weighted $M1$ strength: = $J=0^+,~T=1$ $\rightarrow$ $J=1^+,T=1$ = $ 0.7597 $ = $\mu_N^2MeV$\
$J=0^+,~T=1$ $\rightarrow$ $J=1^+,~T=2$ $1.266$ $\mu_N^2MeV$\
Left Hand Side $\mu_N^2MeV$\
2. $\sum B(E2;1,1)$ $J=0^+,~T=1$ $\rightarrow$ $J=2^+,T=1$ $68.31$ $e^2fm^4$\
3.(a) $\sum B(E2;1,-1)$ $J=0^+,~T=1$ $\rightarrow$ $J=2^+,~T=1$ $33.80$ $e^2fm^4$\
  (b) $\sum B(E2;1,-1)$ $J=0^+,T=1$ $\rightarrow$ $J=2^+,T=2$ $3.203$ $e^2fm^4$\
  (c) $\sum B(E2;1,-1)$ Total $37.003$ $e^2fm^4$\
4. Right hand Side ($\frac{9\chi}{16\pi}=0.0647$): $\mu_N^2MeV$\

A discussion of the calculated B(E2) values
===========================================

Although the main thrust of this work is on $B(M1)$ values, we have established a connection with $B(E2)$ for the orbital case. It is therefore appropriate to discuss the calculated $B(E2)$ values -comparing the behaviours in $^8\mbox{Be}$ and $^{10}\mbox{Be}$, and comparing the different interactions that have been used (see tables $III$ and $IV$.)

In making the comparison between $^8\mbox{Be}$ and $^{10}\mbox{Be}$ we should lump together the
