Precise information of stopping power with dependences on target density and temperature [1] can be utilized for heavy ion fusion target design and heavy-ion-driven high energy density physics experiment.Reliability of stopping power in matter under normal temperature and pressure is established [2],however,the interaction of charged particles with high density and/or hot temperature matter is not yet fully understood.We are interested in stopping power with the dissociation effect of a target because there is no experimental data regardless of the fact that the dissociation of hydrogen is one of the most basic chemical effect.It is expected that the dissociation effect can be observed most significantly for hydrogen,which has only valence electrons.
