THE N(ambu)--J(ona)-L(asinio) MODEL 
  
 
 Here is a brief discussion of the NJL model. This model was 
first formulated BEFORE it was known that  there were quarks. 
The idea of zero range interactions inherent in this model may 
actually be a consequence of  instatons in QCD. Their model in 
its modern form, generally known as the NJL model, with three
quarks per nucleon is turning out to be a remarkably good simple 
approximation to QCD, at least at low energies. By applying this 
NJL model to nuclei, it now appears that this model can, in fact, 
explain many of the things that Maria Mayer discovered empirically,
certainly the pairing, and probably also the strong spin-orbit 
coupling. It appears that there really is some magic in the magic 
numbers.
