Abstract
The nucleon momentum distribution in light nuclei is studied by means of a single particle potential model which consists of an attractive harmonic oscillator potential Valpha = 1/2 m omega 2m omega 2 and also of a repulsive one of the form Vr=B/r2,B>0. The main advantage of this model is that it leads to fairly simple analytic expressions for the nucleon momentum distribution of light nuclei and also for the density distributions and the elastic form factors which in many cases give improved results, in comparison with those obtained with the harmonic oscillator potential. These expressions are quite useful in obtaining, for example, the asymptotic form of eta (k) for large k from which it is seen that the steep decrease of the nucleon momentum distribution observed with the harmonic oscillator model in this region is improved. Numerical results using various least-squares fittings are obtained and discussed for a number of nuclei of the 1s, 1p shell.
