Ramp Potential
Use WKB in one dimension to find the eigenvalues of a particle of mass m in the potential V(x) = F|x|, where F > 0.
SOLUTION
In the present problem, V(x) = F|x| and C = E/F, so
(1)
(2)
Since the integral is symmetric, we can write it as
(3)
Remembering that C = E/F, we obtain the final result:
(4)
