Comment: ``On the computation of molecular auxiliary functions e??′e?‘? and e??μe?‘?a€?

摘要

Guseinov, Mamedov, Kara and Orbay (Pramana a€“ J. Phys. 56, 691 (2001)) propose methods for evaluating the molecular auxiliary functions e??′_e?‘?(e?‘?) and e??μ_e?‘?(e?‘?e?‘?) for the range 17 a‰¤ e?‘? a‰¤ 60 and 25 a‰¤ e?‘?e?‘? a‰¤ 60. However, their procedure for e??′_e?‘?(e?‘?) is not new, and that for e??μ_e?‘?(e?‘?e?‘?) is less ef???cient for their target range than another well-known method. Their approach does have merit for smaller non-zero values of e?‘?e?‘?. Two minor errors in table 1 of their paper are also identi???ed.
