The database of the stopping power has been developed for many elements and compounds under a normal temperature and pressure [2, 3]. However, the stopping cross section can change due to a change of electronic state in the target such as excitation and ionization [4, 5]. Especially, there is few experimental results for the energy loss of charged particles in a dissociated target. Hydrogen is a suitable element to investigate the dissociation effect because it has only one valence electron...Item Open Access Study of Peeling of Single Crystal Silicon by Intense Pulsed Ion Beam(21st International Symposium on Heavy Ion Inertial Fusion.
