Interaction of fast neutrons with /sup 4/He, /sup 3/He, and /sup 1/H: additional and improved data. [20 MeV, differential cross sections, angular distributions]
An improvement of previous elastic scattering data of neutrons in the 20-MeV range was made possible by the improved knowledge of the detection efficiency of the neutron detector. Thus revised absolute differential cross-section data for /sup 3/He(n,n)/sup 3/He and /sup 4/He(n,n)/sup 4/He were obtained with smaller uncertainties. Cross sections of nonelastic n-He reactions were obtained from recent data of the reciprocal reactions by detailed balance calculations. In addition, incomplete angular distributions for the reaction /sup 1/H(n,n)/sup 1/H between 22.5 MeV and 28.5 MeV are presented.
