High-accuracy solution of the three-nucleon problem with realistic NN interactions using the method of hyperspherical harmonics. Comparison with other approaches
- I. V. Kurchatov Atomic Energy Institute (SU)
A set of realistic {ital NN} interactions is used to study the convergence properties of the main characteristics of {sup 3}H and {sup 3}He and the accuracy of reproduction of the three-nucleon wave function in the method of hyperspherical harmonics (MHH). It is shown that a suitably reconstructed MHH basis (projected onto a subspace of essential'' three-particle states) ensures the accuracy of the results and practical convergence of the asymptotic tail of the wave function for a total number of basis states {ital N}{approx lt}1500. The reasons for previous discrepancies between the Feddeev and MHH calculations are determined and the results of the two methods are brought into agreement. The dependence of the characteristics of {sup 3}H and {sup 3}He on the weight of the D wave in the deuteron and on the form of the three-nucleon forces is discussed.
