The hypothesis of charge independence for nuclear phenomena is a symmetry condition
which leads to nontrivial relationships to be satisfied by an extensive class of meson …

A phenomenological analysis of meson production in nucleon-nucleon collisions is
proposed. On the basis of an hypothesis that the production takes place for collisions whose …

The equivalence of pseudoscalar and pseudovector couplings of a pseudoscalar meson
field with a nucleon field is examined. It is found that to the second order in the coupling …

Photomeson production is studied on the basis of the hypothesis of charge independence
combined with the suggestion from meson theory that the meson-nucleon state of angular …

The production of π-mesons in nucleon-nucleon collisions as predicted by scalar meson
theory, pseudoscalar meson theory with pseudoscalar and pseudovector coupling, and …

Experimental evidence pointing to a universal form of interaction for all nuclear particles is
summarized. The form given by Eq.(1) is discussed. It is found to be satisfactory for H 3, He …

Two nucleon forces are studied using a technique with which a detailed account of the
nucleon recoil during meson emission and absorption may be given. The nucleon motion is …

An attempt is made to determine what restrictions are imposed on the nucleon wave
functional by the known values of the nucleon moments and by the neutron-electron …

The present status of the problem of charge dependence is discussed. The information
about the neutron-neutron interaction derived from the two-neutron system, three-nucleon …
