AbstractThe integral relations formalism introduced in [ P. Barletta et al. Phys. Rev. Lett. 103 090402 (2009); C. Romero-Redondo et al. Phys. Rev. A 83 022705 (2011)] and designed to describe 1+N reactions is extended here to collision energies above the threshold for the target breakup. These two relations are completely general, and in this work they are used together with the adiabatic expansion method for the description of 1+2 reactions. The neutron-deuteron breakup, for which benchmark calculations are available, is taken as a test of the method. The s-wave collision between the 4He atom and 4He2 dimer above the breakup threshold and the possibility of using soft-core two-body potentials plus a short-range three-body force will be investigated. Comparisons to previous calculations for the three-body recombination and collision dissociation rates will be shown. ©2012 American Physical Society
