It is proved that the definitions of the norm given by Berggren and Romo are identical. Regularization in ref. 1) with any convergence factor of the form exp (-εrn) [1 < n < 1 2π/ arctg (γ/gk)] leads to the same result. The existence of the norm is also established for the proton. The norm for neutrons is analytically given.
