摘要
We have measured differential cross sections for single and dissociative capture for 25 and 75 keV protons colliding with H-2 and He. Significant differences were found depending on whether the projectile beam was coherent or incoherent. For 75 keV p + H-2 these differences can be mostly associated with molecular two-center interference and possibly some contributions from path interference. For 25 keV (both targets) they are mostly due to path interference between different impact parameters leading to the same scattering angles and, for the H-2 target, possibly some contributions from molecular two-center interference.
