The importance of studying the radiations emitted by nuclei can be understood by considering the kind of information that can be obtained from such a study. Much information can be obtained with a pair spectrograph. The pair process is particularly suited for studying high energy (>3 Mev) transitions since pair production is increasingly probable at higher energies, and since this method makes possible the resolution of complicated spectra. The magnetic lens spectrometer is suited for pair measurements because of its large efficiency for transmitting pairs relative to most other types of spectrometers. Previous measurements have been made with magnetic lens pair spectrometers by Bame and Baggett (Ba 51a) and by D. E. Alburger (Al 52). The purpose of this work was to use a magnetic lens pair spectrograph of improved design to study the pair spectra from some light nuclear reactions. This paper describes a number of experiments which were performed to investigate the pair spectra resulting from the deuteron bombardment of B 10, C12, and F19, and the proton bombardment of B11 and F19. The apparatus and experimental techniques are described, and the results of the experiments are presented.
