Homework Statement
a particle of mass m moves in 1D potential V(x),which vanishes at infinity.
Ground state eigenfunction is ψ(x) = A sech(λx), A and λ are constants.
find the ground state energy eigenvalue of this system.
ans: -ħ^2*λ^2/2m
Homework Equations
<H> =E, H = Hamiltonian.
p= i/ħ∂/∂x[/B]
The Attempt at a Solution
H = p^2/2m+ V(x)
by normalization, [/B]
|A| = λ
i can take care of p^2/2m but what about V(x)
