Differential measurements were made for the process He He yields He He. The differential cross section for this charge transfer was determined at 12 kev, 6 kev, 3 kev, 1.5 kev, 0.75 kev and 0.44 kev. This quantity, in square centimeters, is plotted vs laboratory scattering angle in the range of 1 to 4 degrees. To obtain these results, the experimentally-measured electron capture probability was multiplied by a calculated value of the differential cross section for scattering of the fast particle. The interatomic potential energy function used in these calculations is one which was found experimentally to be in agreement with resonant electron capture data. Author
