A vector product can be written like this. ##(\overrightarrow{l}, \overrightarrow{s}) = \frac{1}{2} (\overrightarrow{j}^2 - \overrightarrow{l}^2 - \overrightarrow{s}^2)## Then maybe just transform the stitching condition? ##\Psi^{'}_{II}(a+0) -\Psi^{'}_{I}(a-0) =...

It is clear that the problem in the potential ##V(r)+W(r)*(l,s)##, but without the (l,s) term: ##V(r)+W(r)##, simply reduces to solving the radial Schrodinger equation. And I understand how to find energy levels in such a task. But what to do when ls interaction also appears in the delta layer?

Hello everyone. Help me solve the problem. I don't understand how to handle this type of task. Find the energy levels of a spin 1/2 particle in a potential well: V(r)+W(r)*(l,s), where V(r<a)=-U, V(r>a)=0, W(r) = q*δ(r-a)
