摘要

We show that the quasi-exactly solvable eigenvalues of the Schr\"odinger equation for the PT-invariant potential V(x)=(ζcosh2xiM)2V(x) = -(\zeta \cosh 2x -iM)^2 are complex conjugate pairs in case the parameter M is an even integer while they are real in case M is an odd integer. We also show that whereas the PT symmetry is spontaneously broken in the former case, it is unbroken in the latter case.
