Interaction range perturbation theory for three-particle problem
I. V. Simenog, D. V. Shapoval
Abstract:
The limit of zero interaction range is correctly defined for a system
of three spinless particles and three particles in a doublet state.
The scattering amplitude is expanded with respect to the interaction
range $r$, and the corrections of order $r\ln r$, $r$, and $r^2\ln^2r$ are
found. An explicit model-independent asymptotic expression is obtained
for the scattering amplitude in terms of the scattering length, and its
accuracy is established.
