Four-body calculation of the four-nucleon system: Binding energies and scattering results

Journal Article · · Phys. Rev. C; (United States)
Using a two-body separable t matrix between pairs, we solve the resulting four-body equations for four spinless bosons in the form that the 2+2 subsystem contribution is treated exactly by the convolution method. The 3+1 subamplitudes are represented as finite rank operators. We compare the utility of these methods both in four-body bound state and scattering calculations. We also develop an approximation that neglects four-body intermediate states in the 2+2 subsystem contribution and compare it with exact results. Finally, we present the results for a four-nucleon calculation with spin dependent s-wave separable interactions between pairs. These formally exact four-body equations are subsequently used to develop one parameter models to describe low energy phase shifts and cross sections for the reactions n /sup 3/H..-->..n /sup 3/H, dd..-->..dd, and dd..-->..p /sup 3/H.
