Evaluating a term in bra-ket notation

  1. Nov 25, 2011 #1
    Hi, i am evaluating the integral [itex]\int_{-\infty}^{+\infty}dE \langle p'|E \rangle \langle E| e^{-iEt/ \hbar} |p\rangle[/itex]

    However, i am unsure how to evaluate [itex]\langle E| e^{-iEt/ \hbar} |p\rangle[/itex] . I am not sure if it is simply [itex]e^{-iEt/ \hbar}[/itex] [itex]\times[/itex] [itex]\langle E|p\rangle[/itex] or something else. Any advice would help. Thank you

    It is, since that exponential is just a number. This post explains bra-ket notation.
