A study was made of the yield in monopolar pairs and in pairs of different orders of multipolarity from the reactions Ca/sup 40/(p,p')Ca/sup 40/ and F/sup 19/(p, alpha )O/sup 16/. To determine the yield, the excitation curves of these two reactions were measured in gamma radiation in internal conversion pairs emitted at THETA = 25 and 65 deg . The curves obtained for the Ca/sup 40/ reaction with protons of 4.8 Mev are given. The number of pairs emitted was too small to consider showing radiative corrections. The curves obtained for the F/ sup 19/ reaction with 1-Mev protons are shown. The relative proportions of gamma rays emitted for proton energies of 842 and 1830 kev are determined. The relative proportion of monopolar pairs was evaluated at 94% and of pairs from the 6.13-Mev level at 6%. (J.S.R.)
