Abstract

Seven theoretical equations for the supermultiplet of negative-parity excited states of ⁴He can be expressed in terms of four parameters. Using four empirically determined energy splitting the following quantities can be predicted: the 0- and 1-, T = 0 states lie near 22 and 28 MeV excitation energy respectively; the ratio of gamma-decay widths of the 1-, T = 1 states at 30 and 26 MeV is approximately 0.4. These predictions are compared with experimental evidence.
