重离子束癌症治疗技术使用质子或能量约为每核子1MeV的氩和氖等离子.重离子治疗比其他方法优越之处在于重离子的大部分能量沉积在很小的空间区域中,即形成布拉格峰.而X射线一旦进入人体便连续地沉积能量.但是对于重离子在分子尺度上,特别是在超过布拉格峰的区域,如何使DNA造成 Heavy ion beam cancer therapy uses protons or argon and neon plasmas with energies around 1 MeV per nucleon. The advantage of heavy ion therapy over other methods is that most of the energy of the heavy ions is deposited in a small area of ​​space called the Bragg peak However, once the X-ray enters the body, energy is deposited continuously, but how heavy ions cause DNA at the molecular scale, especially in areas beyond the Bragg peak
