I have recently finished reading a section on this notation, and while i though i understood it, i now find myself lost
The question is to show that
<m|x|n>
Is zero unless m = n + or - 1
As I understand it so far <m| and |n> correspond to the eigenstates of an arbitrary system and x is just supposed to be the x operator
The only thing i could think to do with his was plug into
[tex]\int[/tex]m*xn dx but that did not help me
I also susspect i need to use that
<m|n>=[tex]\delta[/tex]mn
If anyone could give me a nudge in the correct direction it would be much appreciated.
