다국어 초록 (Multilingual Abstract)

The ^7Li(p,^4He)^4He reaction is used for in searches of universal abundance of Li, nuclear energy stages of ^8Be, and final step of p-p fusion cycle. In this work, we have detected and identified ^3He and ^4He from the ^6Li(p,^3He)^4He reaction and ^4He from the ^7Li(p,^4He)^4He reaction by the energy dependence of the etch pit diameter of the chemically etched tracks in CR-39.
The target was 12㎍/㎠ thin film of natural lithium evaporated in the 10㎛/㎠ carbon backing. The target thickness was measured by Rutherford scattering of proton particles.
For proton energies between 148keV and 462keV, differential cross section, angular distribution, and total cross section were measured. The results were compared with the previous measurements and Gamow-Diagram.
