Mrm. Witwit et Jp. Killingbeck, INNER-PRODUCT THEORY CALCULATIONS FOR SOME RATIONAL POTENTIALS IN 2-DIMENSIONAL SPACE, Physics letters. A, 189(6), 1994, pp. 429-432
The energy levels of a two-dimensional system are calculated for the r
ational potentials V x2)+y4(1+galphay2)]+g(a(xx)x4+2a(xy)x2y2+a(yy)y4)
, using the inner product technique over a wide range of values of the
perturbation parameters (alpha, g) and for various eigenstates. The n
umerical results for some special cases agree with those of previous w
orkers, where available.
