Abstract: The present method is an effort to reduce the requirement of the amount of input data for the calculation of the screening parameter σ1. The method requires the knowledge of no other data except the energy value of the level for the element under consideration. The fresh calculations of the screening parameter σ1 using the new method for the levels L1, L2L3, M1, M2M3, M4M5, N1, N2N3 and N4N5 in the atomic numbers range Z=57 to Z=71, have been described in the present paper.
