Effect of nuclear symmetry in4He on4He and3He on3He collisions at moderate energies

Abstract
The differential cross section for total scattering in 4He on 4He and 3He on 3He collisions has been measured between 0.25 keV and 3 keV. The effect of the nuclear symmetry in these collisions is studied. The amplitudes and the phases of the oscillations in the cross sections corresponding to 4He atoms (bosons) or to 3He atoms (fermions) are compared.
