Abstract

Yield-energy curves for the reaction B11 + H1, using a gas target, have been obtained with an ionization chamber set to count all alpha particles of range greater than 2.0 cm., 2.5 cm., 3.0 cm. and 3.5 cm. The difference curves indicate that alpha particles of all ranges show resonance at 158 + 3 Kev. The energy of the bombarding protons was obtained by using the 330 Kev resonance in the yield of gamma rays from the reaction F19 + H1 as a standard. The apparent half-width for both the fluorine and boron reactions is about 6 Kev.
