The proton transfer reactions, (1) B/sup 10/(N/sup 14/, O/sup 15/)Be/sup 9/, (2) B/sup 10/(N/sup 14/, C/sup 13/)C/sup 11/, and (3)B/sup 11/ (N/sup 14/, C/ sup 13/)C/sup 12/, leaving the reaction products in their ground states were investigated at 27.5 Mev. To distinguish these reactions from other events, the two product particles were detected in coincidence by silicon surface-barrier counters. ln addition, a proportional counter imposed the requirement that the observed particle have the correct charge. Angular distributions (1) and (2) peak at ro= 2.2 fermis when plotted as d sigma /dR/sub min/ vs r/sub 0/, where R of is the distance of closest approach for a Rutherford orbit and r/sub 0/, =R/ sub min/(A/sub 1///sup 1/2/ + A/sub 2//sup 1/3/). The total ground-state cross sections were determined to be (l) 1.34 plus or minus 0.30 mb, (2) 2.19 plus or minus 0.49 mb, and (3) less than 0.3 mb. The data are compared with the predictions of the tunneling theory, and good agreenment is found for the initial rise of the angular distribution. (auth)
