The excitation of γ-radiation in processes of proton capture by light elements

Abstract

In this paper the results of an investigation of the γ-radiations emitted in the process of proton capture by the four light elements, beryllium, boron, carbon and fluorine, are presented. The intensities of the capture radiation for different energies of the incident protons have been determined from the numbers of coincidences produced in a pair of Geiger-Mueller counters. The high sensitivity and low natural effect of this arrangement render it very suitable for the detection of resonance effects of low intensity. Moreover, such weak resonances could be separated from more pronounced ones by the use of very thin targets from which the yield of γ-radiation was relatively low. By this method the excitation curves of the y-ray emission have been determined up to an energy of the incident protons of 10 6 eV, and new resonances have been found for each of the above elements.
