Modified Effective-Range Theory
Developments in effective-range theory as applied to low-energy atomic scattering processes are reviewed. The focus is on the seminal contributions to this theory made by Larry Spruch, who showed how its original form could be extended to account for the presence of long-range forces arising from Coulomb interactions. The influence of this body of work on the very recent developments stimulated...
متن کاملEffective interaction in quasielastic electron scattering calculations
The transverse nuclear response for quasifree electron scattering is discussed. The analysis is done by comparing different calculations performed in the random-phase approximation and ring approximation frameworks. The importance of the exchange terms in this energy region is investigated and the changes in the nuclear responses due to the modification of the interaction are evaluated. The cal...
متن کاملElastic scattering, vibrational excitation, and attachment in low-energy electron-SF6 scattering: Experiment and effective range theory
Cross sections at low energies for vibrationally elastic and inelastic scattering, as well as electron attachment to SF6, have been calculated using a multichannel effective range theory ERT with complex boundary conditions. The most active vibrational modes, the totally symmetric mode 1 and the infrared active mode 3, have been included in the calculation. The ERT parameters were fitted to rep...
متن کاملApplicability of Modified Effective-Range Theory to positron-atom and positron-molecule scattering
We analyze low-energy scattering of positrons on Ar atoms and N2 molecules using Modified Effective-Range Theory (MERT) developped by O’Malley, Spruch and Rosenberg [Journal of Math. Phys. 2, 491 (1961)]. We use formulation of MERT based on exact solutions of Schrödinger equation with polarization potential rather than low-energy expansions of phase shifts into momentum series. We show that MER...
متن کاملModified effective - range theory for low energy e - N 2 scattering
We analyze the low-energy e-N2 collisions within the framework of the Modified-Effective Range Theory (MERT) for the long-range potentials, developed by O’Malley, Spruch and Rosenberg [Journal of Math. Phys. 2, 491 (1961)]. In comparison to the traditional MERT we do not expand the total crosssection in the series of the incident momentum ~k, but instead we apply the exact analytical solutions ...
