Abstract

The elastic differential cross section of 7.0-GeV/c He4 scattered from hydrogen (equivalent Tp=1.05 GeV) has been measured over a range 0.17<~t<~0.85 (GeV/c)2. The experiment has very low background (≤2%), adequate t resolution (≤5%), a good absolute normalization (15%), and a statistical accuracy in the interference region of about 3%. The data show a shallow first minimum and a shape very similar to the recent data from Centres d'Etudes Nucléaires de Saclay.
