McMahon-type asymptotic expansions of the zeros of the Coulomb wave functions
Published 22 Feb 2024 in math.CA | (2402.14537v2)
Abstract: We derive asymptotic expansions of the large zeros of the Coulomb wave functions and for those of their derivatives. The new expansions have the same form as the McMahon expansions of the zeros of the Bessel functions and reduce to them when a parameter is equal to zero. Numerical tests are provided to demonstrate the accuracy of the expansions.
