I have learnt that to transform from one space to another, we can use(adsbygoogle = window.adsbygoogle || []).push({});

g(e) = g(p)/f’, where de/dp = f’

Can we use this relation to transform wavefunctions of energy space to momentum space?

If not, why?

If so, that's very strange as E= p^2/2m and dE/dp= p/m and put into

|psi>=exp(iEt/hbar) ==>|psi>= exp(ipt/mhbar)??
