  In the first part we summarize the status of the nucleon-nucleon (NN) problem in the context of Hamiltonian based constituent quark models and present results for the l=0 phase shifts obtained from the Goldstone-boson exchange model by applying the resonationg group method. The second part deals with the construction of local shallow and deep equivalent potentials based on a Supersymmetric Quantum Mechanics approach.
