Four-Nucleon States in the Continuum: A Means to Probe the Nucleon-Nucleon Interaction

摘要

Four-nucleon states in the continuum are studied through exact microscopic calculations based on the solution of the AGS equations for four nonrelativistic quantum particles. Our studies include calculations of cross sec- tions and analyzing powers for all two-body reactions of interest, but here we only show results for n~3 He→n~3He. The NN interactions we use are Bonn-CD, Nijmegen Ⅱ, and Bonn-B. Compared to exiting quality data, one finds large Discrepancies and some sensitivity to the choice of NN force model.
