H. Konwent et al., A CERTAIN DOUBLE-WELL POTENTIAL RELATED TO SU(2) SYMMETRY, Journal of physics. A, mathematical and general, 28(13), 1995, pp. 3757-3762
In the present paper we analyse a class of partially exactly solvable
one-dimensional double-well potentials. We show how the underlying SU(
2) dynamical symmetry makes it possible analytically to find several e
nergy levels.
