Angular Range

The angular distribution of 1�79 �O� 05 Me V neutrons scattered from 'He has been measured in an effort to settle" a discrepancy in the phase shifts. The laboratory angular range 25� to 135� was covered. The results are compared with differential cross sections computed from the phase shifts of Dodder and Gammel (1952) and Demanins et al. (1962), and the data are seen to agree best with the former.

The D-wave phase shifts for α−α scattering at low energies are obtained from (i) new analyses of the differential cross sections and (ii) the effects of vacuum polarization. The results are −0.4° (−0.4°), −0.2° (−0.4°), +0.2° (−0.4°), −0.2° (−0.2°), and 0.3° (0.2°) for the center-of-mass energies 0.3, 0.425, 0.5, 0.75, and 1.0 MeV, respectively. It is felt that these results are significant.
