[en] In this work, the X-PMSP program, a new user-friendly code for calculating the mass stopping power of elements for charged particles, is introduced with a few sample calculations for each charged particle. The mass stopping power calculations of X-PMSP program are compared with the other mass stopping power results in the literature. These results show that X-PMSP program calculations of mass stopping power for charged particles on elements are suitable. X-PMSP program also contributes to the literature, especially, in radioisotope production, because in addition to proton and alpha charged particles, the mass stopping power of He-3, deuteron, and triton charged particles can be calculated for 98 elements (Z < 98).
