Multichannel Coulomb Scattering with Asymptotic Non-adiabatic Coupling
S. L. Yakovlev, N. Elander
The multi-channel Coulomb scattering problem in the adiabatic representation is considered. The non-adiabatic coupling matrix is assumed to have a non-zero asymptotic behavior at l…
Potential splitting approach for molecular systems
E. Yarevsky, S. L. Yakovlev, N. Elander +1
In order to describe few-body scattering in the case of the Coulomb interaction, an approach based on splitting the reaction potential into a finite range part and a long range tai…
Potential splitting approach to e-H and e-He scattering with zero total angular momentum
E. Yarevsky, S. L. Yakovlev, N. Elander
An approach based on splitting the reaction potential into a finite range part and a long range tail part to describe few-body scattering in the case of a Coulombic interaction is…
Analytic structure and power-series expansion of the Jost function for the two-dimensional problem
S. A. Rakityansky, N. Elander
For a two-dimensional quantum mechanical problem, we obtain a generalized power-series expansion of the S-matrix that can be done near an arbitrary point on the Riemann surface of…
Multi-channel analog of the effective-range expansion
S. A. Rakityansky, N. Elander
Similarly to the standard effective range expansion that is done near the threshold energy, we obtain a generalized power-series expansion of the multi-channel Jost-matrix that can…
Analyzing the contribution of individual resonance poles of the S-matrix to the two-channel scattering
S. A. Rakityansky, N. Elander
A two-channel problem is considered within a method based on first order differential equations that are equivalent to the corresponding Schrödinger equation but are more convenien…
