  • We have measured the widths of the 3/2- ground states of He5 and Li5 using the H3(d,)5He and the He3(d,)5Li reactions at Ed=8.6 MeV. The -ray spectra were fitted with a convolution of the NaI line-shape response function, as measured with the H3(p,)4He reaction, and a Breit-Wigner single-level expression. The widths extracted from the spectra were found to be n=1.360.19 MeV for He5, and p=2.440.21 MeV for Li5. These values, significantly different from previously quoted measurements, lead to reduced widths which are equal to within error, a result which is consistent with the charge-symmetry property of the nuclear force. © 1991 The American Physical Society.
