A Search for Resonance Scattered Protons fromB11andF19

Preliminary work in search of the resonance scattering of protons from ${\mathrm{B}}^{11}$ and ${\mathrm{F}}^{19}$, at the lowest energy resonance in each case, is reported. Such scattering was not observed, but upper limits for it are established and a sensitive method for observing small deviations from Rutherford scattering is described. The proton energy producing the resonance in boron has been determined to be 163±6 kev.
