A Theoretical Prediction of the Neutron-Neutron Scattering Lenght
A theoretical prediction of the neutron--neutron scattering length in the singlet--S state is given. The difference between the neutron--proton and the neutron--neutron scattering lengths is attributed to the charge dependent and charge asymmetric potentials which arise from the isospin mixing of various I=1 and I=0 pseudoscalar and vector mesons, and from the electromagnetic mass splitting of the isovector mesons. It is assumed that the strongly interacting part of the two nucleon potential is the one--boson--exchange--potential. The values of the neutron--neutron scattering length have been found to be dependent on the parameters used in theory.
