Effect of the ^15N(p,α)^12C reaction on the kinetic energy release of water molecule fragmentation
arxiv(2024)
摘要
In this work, we investigated the effect of ^15N(p,α)^12C
reaction produced by the collision between proton and ammonia monohydrate on
the kinetic energy release (KER) of water molecule fragmentation. After the
occurrence of the nuclear reaction, it was found that the charge states q and
the flight speeds v are the main factors affecting the KER of water molecule
fragmentation. With the value of q/v increases, the KER distribution gets
wider and the peak position changes more pronounced. The energy gained by each
fragment is related to the mass of the fragment and the distance of the
fragment from the nuclear reaction. In this study, the fragments with smaller
masses and the distances far away from the nuclear reaction get higher
energies. The fragments of water molecules getting higher energy may induce
other factors affecting the radiotherapy effect, which needs more detailed
investigations in the future.
