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)
