“In the field of lunar surface annihilation radiation research, experts have constructed a quantitative analysis model and used GEANT4 to simulate the differential energy spectrum of gamma rays induced by proton bombardment on lunar rocks, calculating the characteristic peak information of proton induced annihilation radiation in lunar surface rocks. Research has shown that the probability of generating annihilation radiation from cascading showers is positively correlated with the incident proton energy, and the influence of typical lunar rock composition differences on inducing annihilation radiation is not significant.”
