Abstract
A 4He shell-model formalism, including two- and three-body forces, is used to calculate the energy and width of the following T = 1 levels of Fiarman and Meyerhof: 2- (2.6 MeV), 1- (27.4 MeV), 0- (29.5 MeV) and 1- (30.5 MeV). Three¬-body plus two-body forces lead to significant improvements, in comparison with only two-body forces, in the calculation of energy level estimates for the T = 1 states noted above. Improvements in the level width are difficult to ascertain because of the experimental uncertainties in determining the level width.
