Low-Energy Scattering Properties of Ground-State and Excited-State Positronium Collisions
Michael D. Higgins, Kevin M. Daily, Chris H. Greene
Low-energy elastic and inelastic scattering in the Ps(1)-Ps(2) channel is treated in a four-body hyperspherical coordinate calculation. Adiabatic potentials are calculated fo…
Hyperspherical asymptotics of a system of four charged particles
K. M. Daily
We present a detailed analysis of the charged four-body system in hyperspherical coordinates in the large hyperradial limit. In powers of for any masses and charges, the a…
Scattering properties of the polyelectronic system
K. M. Daily, Javier von Stecher, Chris H. Greene
We study the equal-mass charge-neutral four-body system in the adiabatic hyperspherical framework. The lowest few adiabatic potentials are calculated for zero orbital an…
Extension of the correlated Gaussian hyperspherical method to more particles and dimensions
Kevin M. Daily, Chris H. Greene
The solution of the hyperangular Schrödinger equation for few-body systems using a basis of explicitly correlated Gaussians remains numerically challenging. This is in part due to…
