Description

The use of the harmonic oscillator basis in nuclear problems for small values of oscillator radius r0 is studied by the example of a short-range (Gauss) potential. Solutions obtained in the Algebraic Version of the Resonating Group Method (AVRGM) are analyzed and compared to a numerical solution of the Schrodinger equation. Phase shifts for the solutions belonging to the continuum spectrum calculated within different methods are presented
