Molecular Statics (MS) simulations were performed to obtain
information about the stability of point defects in single crystalline
Molybdenum (Mo). Different interatomic potentials were utilized to
determine the formation energies of interstitials and vacancy. Monte
Carlo transport code stopping and range of ions in matter (SRIM) was
used to understand the non ionizing energy loss (NIEL) phenomenon and
number of Frenkel’s pair induced with a dose of 
of He ions carrying energy of 300keV.
Displacement per atom (dpa) and ionization of the specimen are
investigated against depth. SRIM predicted a fall in NIEL, number of
defects and ionization as the impinging ions penetrate deep into the
sample. This study predicts the nature of Mo in a harsh radiation
environment.
