The differential cross section has been measured for elastic scattering of 19.4-Mev protons by nuclei of T, He3, He4, N14, and O16. The proton source was a linear accelerator. The protons were scattered on A gas target at pressures from 520 to 620 mm Hg. The scattered protons were recorded by two CsI(T1) crystal scintillation counters. The differential cross sections for T, He3, and He4 have about the same variation, but the minimum for He4 is somewhat higher and is displaced in the direction of small angles. At small angles the cross section for T is considerably higher than for He3 and He4. |
