Coupling of Angular Momenta Isospin Nucleon-Nucleon Interaction

Interactions from Nucleon-Nucleon Scattering
Nucleon-nucleon scattering data give constrains on the NN-interaction
and allow to determine the parameters in the NN-potential
Some basic features emerging from low-energy nucleon-nucleon scattering are:
• the interaction has a short range of about 1 fm,
• within this range, it is attractive with a depth of about 40 MeV for the larger
distances, whereas
• there is strong repulsion at shorter distances < 0.5 fm;
• it depends both on spin and isospin of the two nucleons.
