摘要: 本文介绍一个模拟具有给定动能的离子在固体中传输及引起靶原子位移过程的Monte carlo程序,包括工作原理、物理模型和计算实例等。本程序采用两体碰撞近似研究α粒子轰击无定形靶的位移原子深度分布,并分析了位移原子深度分布与固体中能量沉积的关系。

Abstract: A Monte Carlo code is described which simulates the displacement process and the transmissions of energetic particles in solids by ion bombardment, including the operating principle, the physics model and the computing examples. Based on the binary collision approximation, the depth distributions of displasced atoms in amorphous targets induced by α particles are investigated, and the relations between the depth distributions of displaced atoms and energy deposition in solids are discussed.

Key words: amorphous target, displaced atoms, Monte Carlo simulation, energy deposition
