Abstract
The nucleon-nucleon interaction is constructed by means of the
J
-matrix version of inverse scattering theory. Ambiguities of the interaction are eliminated by postulating tridiagonal and quasi-tridiagonal forms of the potential matrix in the oscillator basis in uncoupled and coupled waves, respectively. The obtained interaction is very accurate in reproducing the
NN
scattering data and deuteron properties. The interaction is used in the no-core shell model calculations of
3
H and
4
He nuclei. The resulting binding energies of
3
H and
4
He are very close to experimental values.
