Improving the Feshbach-Rubinow approximation

arXiv:nucl-th/0508059 · doi:10.1103/PhysRevC.72.034007

Abstract

The binding energy of three identical bosons is estimated by coupled differential equations which generalise the Feshbach--Rubinow approximation. This method turns out to be rather efficient, especially in the limit of vanishing binding.
