Resumen
Using one of the differential equation that V(x) satisfies, at the present paper we obtain m(a,x) as a function, not only of a, but also of x. Kielkopf first propose m(a,x) based on numerical arguments. We find that,the Voigt function calculated with the expression m(a,x) we have obtained in this paper, deviates from the exact value less than m(a) does, specially for high |x| values.
