Scattering-Angle Dependence of Doubly Differential Cross Sections for Fragmentation of H₂ by Proton Impact
Physical Review A - Atomic, Molecular, and Optical Physics
Abstract
We have measured double differential cross sections (DDCS) for proton fragment formation for fixed projectile energy losses as a function of projectile scattering angle in 75 keV p + H2 collisions. An oscillating pattern was observed in the angular dependence of the DDCS with a frequency about twice as large as what we found earlier for nondissociative ionization. Possible origins for this frequency doubling are discussed.
