We have proposed the semi-empirical formula for pair production cross-section in nuclear and electric field of atoms with atomic number [Formula: see text] in the energy range of [Formula: see text]. To validate the present formula, the values produced by the proposed formula are compared with the available experiments. The percentage of deviation of present formula pair production was found to be less than [Formula: see text]. The present formula is useful in the fields of radiation, particle and Nuclear Physics.
