Continuum calculations of photonuclear reaction cross sections in4He

Abstract
The authors have tested, in the case of the 4He nucleus, the method of Delsanto and Quarati (see ibid., vol.2, p.161 (1976)) for elimination, from continuum calculations of nuclear reaction cross sections, of spuriosities deriving from the centre-of-mass motion. The results seem to indicate that the method is effective and the overall agreement satisfactory.
