Abstract

A G-matrix interaction applicable to nuclear states of the configuration (1s)4(1p)A−4 is obtained by fitting the position of energy levels in the 1p shell. In addition to a simple two-body potential the three-body vector force previously shown to arise from second-order effects of the tensor force is included. A total of 18 potential parameters are fitted to 34 low-lying energy levels to an rms deviation of 0.381 MeV. An additional twelve known levels are predicted to an rms deviation of 0.402 MeV. The only well established levels for which a reasonable fit is not obtained are the strong α-emitting states in 8Be and 12C. It is concluded that α-clustering makes a significant contribution to the energy of these α-decaying states.
