H2(p, 2p)nCross Sections for ConstantNNRelative Energies

Measurements and various $s$-wave model calculations of $p+d$ breakup cross sections were made along constant-relative-energy loci as suggested by Jain, Rogers, and Saylor. The measurements utilized special gas scattering apparatus to accurately measure cross sections in the vicinity of destructive interference minima. The data agreed with the most realistic of the models used except at the position of the interference minimum where a discrepancy of a factor of 3 was found.
