Abstract

We develop a variational method to obtain accurate bounds for the eigenenergies of H = -Delta + V in arbitrary dimensions N > 1, where V(r) is the nonpolynomial oscillator potential V(r) = r(2) + 1+gr(2)/lambda r(2), lambda is an element of (-infinity,infinity),g > 0. The variational bounds are compared with results previously obtained in the literature. An infinite set of exact solutions is also obtained and used as a source of comparison eigenvalues.
