Implications of the experimental results on the photodisintegration of /sup 4/He

· Phys. Rev. C; (United States)
The photoproton and photoneutron cross sections for /sup 4/He are evaluated in the light of several recent measurements, and are found to be substantially different in the energy region below 30 MeV. Because these cross sections are dominated by ..delta..S = 0, ..delta..T = 1 E1 transitions, this result implies strong isospin mixing in the four-nucleon system. Furthermore, since available continuum shell-model calculations including Coulomb effects predict only small differences in the photoproton and photoneutron cross sections except near threshold, this result suggests that a nonzero charge asymmetry is present in the nuclear force.
