Abstract

The reaction He4 (He4, He4) He4* was investigated using a 64-MeV α-particle beam. Absolute differential cross sections for the state near 20-MeV excitation are reported for the angular range 12.5°<θc.m.<74°. We measure the excitation energy of this state to be 20.28±0.05 MeV and the width to be 0.41±0.05 MeV. The shape and position of this state are shown to be consistent with an analysis based on the known properties of low-energy pH3 scattering.
