14 16 22 -06 -2017 | 16 Conclusion ü For small azimuthal opening angles, the calculation including 3 NF, the agreement is worse than calculation without the 3 NF. ü The effect of 3 NFs is predicted to be small, although adding a 3 NF to the NN potentials helps to bridge the gap between the data and the NN calculations.
