2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/81933We report on a consistent, microscopic calculation of the bound and scattering states in the 4He system employing modern realistic two-nucleon and three-nucleon potentials in the framework of the resonating group model (RGM). We present for comparison with these microscopic RGM calculations the results from a charge-independent, Coulomb-corrected R-matrix analysis of all types of data for reactions in the A=4 system. Comparisons are made for selected examples of phase shifts and measurements from reactions sensitive to three-nucleon force effects.9 pages, 4 figures, HLRB/Konwihr workshop, Oct. 10-11, 2002, Garching/Germany, uses svmult.cls styleNuclear Theorytext
