Tree-particle integrals with spherical Bessel and Neumann functions
Abstract
A few approaches are derived to calculate three-particle integrals which include spherical Bessel functions of the first and second kind, i.e., the j(V r) and n(V r) functions. Such integrals are important in applications to various problems known in atomic and nuclear physics. In particular, these integrals are needed in accurate computations of the photodetachment cross-section(s) of the negatively charged hydrogen ions.
