Schrodinger equation in cylindrical coordinates.

Click For Summary
SUMMARY

The discussion focuses on formulating the Schrödinger equation in cylindrical coordinates for a nuclear case, incorporating the total potential defined by the Woods-Saxon potential, spin-orbit potential, and Coulomb potential. The equation is expressed as: $$[-\frac{\hbar^2}{2m}(\frac{\partial ^2}{\partial r^2}+\frac{1}{r}\frac{\partial }{\partial r}+\frac{1}{r^2}\frac{\partial^2}{\partial \varphi^2 }+\frac{\partial^2}{\partial z^2})+V_{tot}]\Psi (r, \varphi, z)=E \Psi (r, \varphi, z)$$. The user seeks guidance on explicitly defining the total potential, V_{tot}, in cylindrical coordinates.

Hi guys!
For nuclear case, I need to write an Schrödinger equation in cylindrical coordinates with an total potential formed by Woods-Saxon potential, spin-orbit potential and the Coulomb potential.

Schrödinger equation can be written in this form:

$$[-\frac{\hbar^2}{2m}(\frac{\partial ^2}{\partial r^2}+\frac{1}{r}\frac{\partial }{\partial r}+\frac{1}{r^2}\frac{\partial^2}{\partial \varphi^2 }+\frac{\partial^2}{\partial z^2})+V_{tot}]\Psi (r, \varphi, z)=E \Psi (r, \varphi, z)$$


How can I write explicitly ##V_{tot}##?

Someone could give me some ideas on how to write Woods-Saxon, spin-orbit, Coulomb potentials in cylindrical coordinates?

Thanks!
