NONLOCALITY IN THE NUCLEON-NUCLEON INTERACTION DUE TO MINIMAL-RELATIVITY FACTORS - EFFECTS ON 2-NUCLEON OBSERVABLES AND THE 3-NUCLEON BINDING-ENERGY

Minimal-relativity factors, when multiplied to a static local meson-ex change nucleon-nucleon potential, lead to a nonlocal potential. It is shown that the nonlocality can be represented by an analytically given nonlocality function, which has a width inversely proportional to the nucleon mass and which tends towards delta(r(-->/) - (r) over right a rrow), the usual locality condition, in the limit of the nucleon mass going to infinity. Consequences of this particular type of nonlocality for two-nucleon observables and for the three-nucleon binding energy are investigated along with a Malfliet-Tjon-type potential. After read justing the potential parameters of the nonlocal potential such that i ts two-nucleon properties are well matched to the ones of the static l ocal potential the effect of the nonlocality on the three-nucleon bind ing energy essentially vanishes.
