how can i know the number of boundstate of a particle acting under a deltafunction potential?
Draw the wavefunction. How many ways are there to do this?
Or if you want to go the whole nine
1) Write Schrodinger's equation
2) Solve Schrodinger's equation with the appropriate boundary conditions (Psi continuous at x=0, dPsi/dx discontinuous by a certain amount), and the condition that E<0
3) Show that there is in fact only one such state
