NN Data Bases and References
•CNS @ George Washington U.
–CNS maintains the world data base for experimental  NN  etc. Phase shifts
•NN On-line from Netherlands
–They maintain NN Nijmegen Potentials, Phase shifts, Deuteron Properties.
•U of Hamburg from Germany
–They have potentials obtained by inverting experimental phase shifts.
–The have also greatly extended my work on SWEPs they call them One Solitary Boson  Wave Exchange Potentials (OSBEPs).
