Coordinate representation ##\psi=\psi(x)##(adsbygoogle = window.adsbygoogle || []).push({});

Momentum representation ##\psi=\psi(p)##

Fourier transform

[tex]\psi(p)=\frac{1}{\sqrt{2\pi\hbar}}\int^{\infty}_{-\infty}\psi(x)e^{-\frac{ipx}{\hbar}}dx[/tex]

I'm confused with this ##\hbar##? Why not

[tex]\psi(p)=\frac{1}{\sqrt{2\pi}}\frac{1}{\hbar}\int^{\infty}_{-\infty}\psi(x)e^{-\frac{ipx}{\hbar}}dx[/tex]?
