Pions in the deuteron

A potential containing a one-pion-exchange tail and regularized at the origin by means of three parameters is used to construct several families of deuteron wave functions, which are employed in the assessment of the influence of the inner parts of the potential over observables such as {ital r}{sub...

Description
Summary:A potential containing a one-pion-exchange tail and regularized at the origin by means of three parameters is used to construct several families of deuteron wave functions, which are employed in the assessment of the influence of the inner parts of the potential over observables such as {ital r}{sub {ital m}}, {eta}, and {ital Q}. The off-energy shell extrapolation of the results is considered, so as to provide guidelines for the treatment of other systems such as the triton. We also show that, provided the central potential contains a one-pion-exchange tail, the value of {eta} is determined with great precision by just the inner part of the tensor component of the interaction.
