Gamma-ray excitation curves from B 10 ( p , α 1 γ ) Be 7 and B 10 ( p , p 1 γ ) B 10 reactions

The $\ensuremath{\gamma}$-ray yield from 2.00 to 4.1 MeV proton bombardment of $^{10}\mathrm{B}$ has been investigated. A single resonance is observed at ${E}_{p}=3.03$ MeV in the yield of 0.43 MeV $\ensuremath{\gamma}$ rays.NUCLEAR REACTIONS $^{10}\mathrm{B}$($p$,$\ensuremath{\alpha}\ensuremath{\gamma}$)$^{7}\mathrm{Be}$ and $^{10}\mathrm{B}$($p$,${p}^{\ensuremath{'}}\ensuremath{\gamma}$)$^{10}\mathrm{B}$, $E=2.0\ensuremath{-}4.1$ MeV; measured ${E}_{\ensuremath{\gamma}}$, ${I}_{\ensuremath{\gamma}}$. $^{11}\mathrm{C}$ deduced levels.
