The Vector Analyzing Power in the 2H(\(\overrightarrow d \) ,p)3H Reaction between 15 and 25 MeV

The charge-symmetric reactions 2H(d,p)3H and 2H(d,n)3He have been studied in considerable detail at energies up to 15 MeV1,2). Differential cross sections, nucleon polarizations, and deuteron vector and tensor analyzing powers have been measured, and differences in these observables for the two reactions have been examined for evidence of a possible deviation from the charge symmetry of the nuclear interactions. The more recent comparisons and calculations3) have been able to explain the observed differences between the two reactions in terms of the Coulomb effect, including the Q-value difference.
