FORM FACTOR OF 3He WITH THE HAMADA-JOHNSTON POTENTIAL

Abstract

Publisher Summary The charge form factor, Coulomb energy, and root-mean-square charge radius of 3He are calculated with a number of variational wave function. The wave functions are expanded in terms of the polynomials of interparticle distances with proper symmetry. The 170-term wave functions are calculated with the Hamada-Johnston potential. Nonlinear variational parameters in the exponential tails are varied to give the various wave functions. Binding energy for 3H obtained for those wave functions ranges between −4 MeV and −6.1 MeV. Coulomb energy for the 3He varies from 0.64 MeV to 0.71 MeV. Coulomb energy is calculated with a point proton. The wave function with good binding energy does not give better agreement with other experimental data except the Coulomb energy. The chapter presents that the binding energy and the minimum in the charge form factor are systematically correlated. Lower binding energy wave functions are more favored by most of the experimental data.
