How important is the three-nucleon force?
Abstract
Description
By calculating the contribution of the $π-π$ three-body force to the three-nucleon binding energy in terms of the $πN$ amplitude using perturbation theory, we are able to determine the contribution of the different $πN$ partial waves to the three-nucleon force. The division of the $πN$ amplitude into a pole and nonpole gives a unique procedure for the determination of the $πNN$ form factor in the model. The total contribution of the three-body force to the binding energy of the triton is found to be very small.
