The initial conditions y(0)=1 and y'(0)=0 are fine and help in solving the Schrödinger equation, however,

**studying free electrons**, the equation cannot be solved neither for the particle in the box , or for a finite linear motion harmonic oscillator as far as I can see from the literature.

When I solve the eqn, HY=EY , I can set E= p/2m or E= ground state energy. In either cases, I get a result where some unknown constant appears.

This constant can be solved using the Born Sommerfeld condition, but because the solution is not square integrable, it gives complex values.

How can I solve the unknown constant for a solution of the Schrödinger eqn. where the above given initial conditions are used?

Thanks!
