1. The problem statement, all variables and given/known data Consider this situation, V(x)=λδ(x) ,-a<x<a. V(x)=∞,x>a or x<-a. How to find the eigenvalue and eigen wavefuntion of the Hamiltonian. 2. Relevant equations i can only reder to stationary Schrodinger equation. 3. The attempt at a solution when it is ouside the well(x>a or x<-a), the wave function is zero. But when it is inside the well, i just do not know how to solve the Schrodinger function because i do not know how to deal with the dela potential.
