Bipartition model of ion transport: An outline of new range theory for light ions
Journal Article

· Phys. Rev. B: Condens. Matter; (United States)
Extending the bipartition model of electron transport to the case of light-ion transport, the approximate solution for the light-ion distribution function under the continuously-slowing-down approximation has been developed so as to go a step further in obtaining the light-ion-range profile and other transport quantities (Luo Zhengming, Phys. Rev. B B32R, 812 (1985); B32R, 824 (1985)). The comparison with existing theories and experiments shows that the new theory not only has the precision which can match with that of the current-transport theory, but is far more flexible in describing the transport process of energetic ions in matter.
