Abstract

The differential cross section of the 2H(α, t)3He reaction has been measured between θc.m. = 17° and 152° at an incident α-energy of 48.25 MeV. This represents a test of the Barshay-Temmer theorem, which requires symmetry of the angular distributions about 90°. Earlier experiments have found no asymmetry at lower incident α-energies and deviations of up to 10% at higher incident energies. We find deviations from symmetry as large as 20% at some angles.
