    "abstract": "We carry out a study of the study of the $Q \\cdot Q$ interaction in a model\nspace which consists of several nucleons in an open shell and all $2 \\hbar\n\\omega$ excitations. This interaction is $ -t (X_o/2) Q \\cdot Q$, where for t=1\nwe get the `accepted strength\u0027. In the $0p$ space, the spectrum would scale\nwith $t$. In this space, the $2^+_1$ and $2^+_2$ states of $^{10}$Be are\ndegenerate, as are the [330] and [411] sets of $J=0^+, 1^+$ and $2^+$ triplets.\nWhen $2 \\hbar \\omega$ admixtures are included, the degeneracies are removed.\nFor $t \\geq 1.8$ we have new ground state and a new $2_1^+$ state. These are\nstates in which two particles are excited from the $0p$ to the $1s-0d$ shell.\nThere is no mixing of these 2p-2h states with the other states. For these 2p-2h\nstates the occupancy for 0s,0p,1s-0d and 1p-of are 4,4,2 and 0 respectively.",
