an electron moves in 1D and is confined to the right half (x>0)
potential: V(x) = -(e^2)/(8piEx) E is the permittivity of free space
the ground state wave function is Nxe^(-ax)
N is normalization constant, and a is another constant needed to be determined
time independent schrodinger: (-h^2/2m) (d^2Si/dx^2) + V*Si = E*Si
The Attempt at a Solution
The first part of this problem tells my to substitute the ground state wave function in the appropriate TISE to determine a.
I am completely lost on this one because I usually substitute V(x) into the TISE to determine a and I never had to do it the way they are describing. I tried to sub the wave function into the standard TISE and got:
(ax+2)/a^2 = (E-V)(-2xm)/(h^2) - this is after doing the double derivative of the wave function etc.
However I still cant solver for just a doing the way I tried.
Please help, thanks.
