EFFECTS OF THE 3-NUCLEON FORCES DUE TO PI-MESON AND RHO-MESON EXCHANGES IN THE 3-NUCLEON CONTINUUM

Using the Bonn B nucleon-nucleon potential and the Tucson-Melbourne fa mily of pi-pi, pi-rho and rho-rho three-nucleon forces we solved the 3 N Faddeev equation below and above the deuteron breakup threshold. For different elastic scattering and breakup observables we looked for th e effects caused by adding consecutively the above 3N forces. The larg est effects were found for the pi-pi three-nucleon force. The influenc e of pi-rho exchange was generally found to be smaller than pi-pi and it acts in opposite direction. The effect of the rho-rho three-nucleon force was found to be always negligible. Adding pi-rho and rho-rho th ree-nucleon forces does not explain the analyzing power puzzle in the low energy nucleon-deuteron elastic scattering.
