The ground state solution of which would (with n = 0) read

with an eigenvalue 

Nonetheless, the boundary condition on the wave function 

on the x -axis would mandate 

Feasibly, the satisfaction of this condition is obviously achievable when λ > 2. This would imply that 

At this point, we choose to stick with the continuity conditions at the hetero- junction boundaries between two crystals and take α = γ ⇒ β = − 1 − 2 α to imply 

This suggests, in addition to von Roos constraint (2), new constraints α = γ < − 3 / 4 or α = γ > 0 on the ambiguity parameters. In table 1, we list the
