RESONANCE 3-]3 SCATTERING AND STRUCTURE OF THE EXCITED-STATES OF A = 6 NUCLEI

Three-particle resonance states of A = 6 nuclei are studied by the met hod of hyperspherical harmonics. The effective three-particle potentia ls for the T = 1 multiplet of A = 6 nuclei and the three-particle scat tering phase shifts are analyzed, together with the results of our cal culations-the three-particle amplitudes, positions and widths of the r esonances, and the resonance behavior of the wave functions in the int ernal and external regions. The characteristics of the three-particle resonances calculated in the modified Feshbach approach are discussed.
