Abstract
The using of heavy ions in the treatment of cancer tumors allows for accurate radiation of the tumor with minimal collateral damage that may affect the healthy tissue surrounding the infected tissue. For this purpose, the stopping power and the range to which these particles achieved of Neon (Ne) in the ovary tissue were calculated by programs SRIM (The Stopping and Range of Ions in Matter), (SRIM Dictionary) [1] ,(CaSP)( Convolution approximation for Swift Particles )[2] which are famous programs to calculate stopping power of material and Bethe formula , in the energy range (1 - 1000) MeV .Then the semi - empirical formulas to calculate the stopping power and range of Neon ions in the ovary tissue were founded from fitting for average the values which calculated by using these programs using (MATLAB2016) program, the maximum value of energy for Neon ions can lose along its path in ovary tissue is founded and the range correspond to this value, the maximum range for Neon ions can reached in the ovary tissue is founded too , the importance of research is to know the data of these particles and their use in treatment without causing a bad effect on the patient.
