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 family of pi-pi, pi-rho and rho-rho three-nucleon forces we solved the 3N Faddeev equation below and above the deuteron breakup threshold. For different elastic scattering and breakup observables we looked for the effects caused by adding consecutively the above 3N forces. The largest effects were found for the pi-pi three-nucleon force. The influence 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 three-nucleon forces does not explain the analyzing power puzzle in the low energy nucleon-deuteron elastic scattering.
