    Does anyone has proof of radial momentum operator as an Hermitian operator? Thanks.

    By the radial momentum operator you mean the momentum conjugate to [tex]r[/tex]? Sandwich it between two wavefunctions, integrate by parts, and all should work out. Remember the integration measure contains a factor of [tex]r^2[/tex].
