Deuteron Capture by Deuterons and the Structure of 4He

Abstract

The four-body scattering matrix describing the various scattering states of two protons and two neutrons is analysed to see what information can be gained on the structure of the bound state, 4He. It is found that an estimate can be given of the fraction of time that 'He appears as two deuterons; this estimate is· in turn used to calculate the cross sections for the process d(d, y)'He. The low energy n-3He singlet elastic scattering parameters appear to be fairly well determined by the data studied.
