The Scattering of Deuterons by Helium at Deuteron Energies from 0.9 to 3.5 Mev

The differential cross sections for the elastic scattering of deuterons by helium have been measured for deuterons of 0.9 to 3.5 Mev over an angular range from 15^∘{} to 160^∘{} in the center-of-mass system. The probable error in the absolute values of the cross sections is 3 percent or less. For angles greater than 60^∘{} the cross sections are roughly independent of angle except at 3.5 Mev where they decrease with increasing angle up to 90^∘{} and increase beyond.
