Dick,
Well, this is how I have always encountered the overlap integral - you're given a wavefunction and can use it to e.g. calculate the probability of finding the system in a particular eigenenergy. I'm trying to broaden my horizons though - where does PSI come from? I seem to remember...
As noted above, I'm new to the board and just checked the forums to see my question moved to this Homework section. Just to note that this is not part of any assignment - I'm trying to clear up gaps in my understanding.
Thanks
First post and not used to the symbols that I have seen used in posting formulae, so please be patient! :smile:
The probability of obtaining the ith energy eigenvalue Ei is given by the square modulus of the integral psi_i*(x)PSI(x,t)dx where PSI(x,t) is the wave function of the system...
