Effects of nonlocal one-pion-exchange potential in deuteron

PDF Version Also Available for Download.

Description

The off-shell aspects of the one-pion-exchange potential (OPEP) are discussed. Relativistic Hamiltonians containing relativistic kinetic energy, relativistic OPEP with various off-shell behaviors and Argonne v{sub 18} short-range parameterization are used to study the deuteron properties. The OPEP off-shell behaviors depend on whether a pseudovector or pseudoscalar pion-nucleon coupling is used and are characterized by a parameter {mu}. The authors study potentials having {mu} = {minus}1, 0 and +1 and they find that they are nearly unitarily equivalent. They also find that a nonrelativistic Hamiltonian containing local potentials and nonrelativistic kinetic energy provides a good approximation to a Hamiltonian containing a ... continued below
