# Evaluating a term in bra-ket notation

## Main Question or Discussion Point

Hi, i am evaluating the integral $\int_{-\infty}^{+\infty}dE \langle p'|E \rangle \langle E| e^{-iEt/ \hbar} |p\rangle$

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