Abstract
The proton transfer reactions, (1) (,), (2) (,), and (3) (,), leaving the reaction products in their ground states were investigated at a mean energy of the incident nitrogen ions of 27.5 Mev. To distinguish these reactions from other events, the two product particles were detected in coincidence by silicon surface-barrier counters. In addition, a proportional counter imposed the requirement that the observed particle have the correct charge. Angular distributions (1) and (2) peak at fermis when plotted as vs , where is the distance of closest approach for a Rutherford orbit and . The total ground-state cross sections were determined to be (1) 1.34±0.30 mb, (2) 2.19±0.49 mb, and (3) less than 0.3 mb. The data are compared with the predictions of the tunneling theory, and good agreement is found for the initial rise of the angular distribution.
