Mrm. Witwit, INNER PRODUCT THEORY CALCULATIONS FOR DOUBLE-WELL POTENTIALS IN 2-DIMENSIONAL SPACE, Indian Journal of Pure & Applied Physics, 33(4), 1995, pp. 179-184
The renormalized inner product perturbation technique is used to compu
te the energy levels for a double-well potential V(x,y,Z(2), )+y(2)+l
ambdaa(xx)x(4)+2a(xy)x(2)y(2)+a(yy)y(4) in a two-dimensional space.
Results are produced for a wide range of parameters Z(2),lambda and th
e state numbers (n(x) and n(y)).
