Remarks on the Adiabatic Nuclear Potential

概要

We discuss on the validity and approximation method of the adiabatic nuclear potentials, especially of the fourth order nuclear potential derived from pseudoscalar meson theory^<5)>. In § 2, it is shown that effects of time component of pseudovector coupling on the pseudoscalar meson potential are not large when distance between two nucleons is larger than about half of the force range. In § 3, time variation of nucleon spin and τ-spin are evaluated for phenomenological and meson potentials, and critical radii for their applicability are derived. In § 4, implications of the velocity-dependet forces in the interior region are discussed, and largeness of the purely quantum mechanical effects in the meson theory is pointed out. Hamiltonian for a two nucleon system in the intermediate coupling approximation is given. In § 5, features of the meson-nucleon interaction are compared with that of the photon-electron interaction. It is pointed out that the transition matrix of the nucleon-nucleon collision is not analytic with respect to nucleon energy at the threshold for meson production. An ambiguity occurs when one intend to calculate the sixth order nuclear potential.
