Estimate of ground state energy for the Yukawa potential

[L_landau]

I’ve seen the uncertainty principle used to calculate the ground state energy for things like hydrogen and the harmonic oscillator, but can this be done for the Yukawa potential where you have an exponential?

Can you give a specific reference?
