Test of forbidden state NN potential in the 3N system
Significant underbinding for the triton of a quantum-chromodynamically motivated realistic NN potential containing a superdeep short-ranged attraction and a forbidden state in the S-italic waves has been reported from a previous Faddeev calculation. In the present paper, this feature is reproduced with a simple S-italic-wave-interaction model of this NN potential, generalized into a wide range in the form of a short distance node, and explained in terms of short-ranged NN D-italic-wave components which the nodal S-italic-wave components introduce inevitably through the three-body kinematics. The strengths of the NN D-italic-wave interactions are estimated to be not sufficient to compensate for the kinetic energies arising from these D-italic-wave components, which means a significant loss for 3N binding. This is in sharp contrast to the strong 3..cap alpha.. binding in the forbidden state ..cap alpha cap alpha.. potential model which is supported by strong D-italic- and G-italic-wave interactions. The present study indicates that a noticeable short distance node in the 2N wave function is unlikely.
