Interpretation of ion-range recoil data obtained from activated-foil measurements of nuclear excitation functions

Ion-range recoil data were obtained during activated-foil measurements of excitation functions for proton-, deuteron-, and triton-induced reactions on selected targets. These data were analyzed by using the Lindhard, Scharf, and Schiott range-energy theory. An important feature of our analysis was t...

Description
Summary:Ion-range recoil data were obtained during activated-foil measurements of excitation functions for proton-, deuteron-, and triton-induced reactions on selected targets. These data were analyzed by using the Lindhard, Scharf, and Schiott range-energy theory. An important feature of our analysis was the use of angular distributions from the recent Kalbach systematics based on multistep compound and multistep direct reactions. Furthermore, we used the ({ital p},{ital n}) data to fix the parameters of LSS theory, and then applied the theory to ({ital d},{ital n}), ({ital d},2{ital n}), ({ital t},2{ital n}), ({ital t},{alpha}) and ({ital d},{alpha}) reactions. The adjustments to the LSS-theory parameters were less than 10%. The comparisons of the data with calculations demonstrate several important aspects of the reaction mechanisms, e.g., transition from equilibrium to direct reaction, breakup of the deuteron and triton in the reaction entrance channel, and pickup for triton-induced reactions. Overall, the ion-range measurements give a consistent picture of the reaction mechanisms involved.
