Abstract:

Differential measurements of the electron capture probability P are made for protons scattered from atomic hydrogen targets. The incident proton energy ranges from 150 keV down to 0.130 keV and the scattering angle is varied between 0.2 deg. and 6.0 deg. Seven sharply resonant peaks of P are found, their location depending on both energy and angle. For example, when the scattering angle is held at 6 deg. the peaks are found at 21, 3.9, 1.7, 0.90, 0.54, 0.36, and 0.19 keV, and when the energy is fixed at 0.250 keV, peaks are found at 0.7, 1.4, 2.6, and 4.5 deg. In some cases the equivalent collision with deuterium, D-D, is used to augment the range of the measurements. These data extend those reported by Lockwood and Everhart 1962 who studied this same phenomenon in H-H collisions over a smaller range in energy and at fixed 3 deg. scattering angle. Relative differential-cross-section data are presented also which show a change in slope with the onset of rainbow-angle scattering conditions. Author
