Abstract

A determination of the differential cross section for the elastic scattering of protons by carbon twelve at angles of every ten degrees in the center of mass system from 30 to 160 degrees has been made near the 460 kev resonance in C[superscript 12](p[...]). A phase shift analysis of the carbon twelve data has been performed.

The differential cross section for the elastic scattering of protons by carbon thirteen has been determined in the energy range from 450 kev to 1.6 mev at angles of 50, 90, 120, and 160 degrees in the center of mass system. Anomalies were found in the scattering at 0.556, 1.158, 1.465, and 1.550 mev. A qualitative discussion is presented on these states in the compound nucleus, nitrogen fourteen.

An electrostatic generator was used to produce a beam of protons of accurately known energy. A double focusing, variable angle, magnetic, proton spectrometer was used to obtain a momentum analysis of the scattered particles. A magnetometer and magnet control circuit for the spectrometer are discussed.
