Comment on "Energy levels, oscillator strengths, and transition probabilities for sulfur-like scandium, Sc~VI" by El-Maaref et al.\, [Indian J. Phys. {\bf 91} 1029 (2017)]

Comment on "Configuration interaction calculations and excitation rates of X-ray and EUV transitions in sulfurlike manganese" by El-Maaref et al. [J. Elect. Spectrosc. Related Phen. 215 (2017) 22]

In one of the papers, El-Maaref et al. [J. Elect. Spectrosc. Related Phen. 215 (2017) 22] have reported results for energy levels, oscillator strengths (f-values), radiative rates (A-values), collision strengths ($Ω$), and excitation rates for transitions in S-like Mn~X. However, except for energy levels their results are restricted to only a few transitions and hence have limited application. Furthermore, most of their results have scope for improvement, but for $Ω$ are not correct as these have been found to be overestimated by an order of magnitude. In this comment we discuss the discrepanc…
