Abstract

The cross sections for the production of

{}^{11}C

and

{}^{7}{Be}

by protons from a

{}^{14}N

target has been measured at energies from 5-24 MeV for

{}^{11}C

and 13-42 MeV for

{}^{7}{Be}

. A sharp rise above the thresholds for the

{}^{14}N (p, α)

and

{}^{14}N (p, 2 α)

reactions was observed, with maxima, respectively, around 200 and 45 mb.
