Dissertation/Thesis Abstract

Resonances of the e-Ps system by solving the Faddeev-Merkuriev integral equations
by Marotta, Angela Rose, M.S., California State University, Long Beach, 2009, 29; 1466333
Abstract (Summary)

An efficient way of locating resonances in atomic three-body systems is presented. The homogeneous Faddeev-Merkuriev integral equations are solved by applying a separable expansion approximation on the potential terms in the Coulomb Sturmian basis. This approximation transforms the integral equations into a matrix equation. The complex energies are searched for as the complex zeros of the Fredholm determinant. The matrix elements of the three-body Coulomb Green's operator are calculated as the contour integral of two-body Coulomb Green's operators. Finally, the resonances of the e-Ps system of angular momentum L = 1 for natural and unnatural parity are presented.
