The Impact of Deuteron Breakup in the Field of 90Zr and 116Sn Targets

The role of continuum coupling to the breakup of the deuteron is clearly shown through microscopic continuum discretized coupled channel (CDCC) calculations carried out with and without this coupling. The analysis was further extended to construct an effective potential (U_eff) from the sum of cluster folding (CF) and dynamical polarization (DPP) potentials that allow the continuum coupling to be more easily visualized. The considered d + ⁹⁰Zr and ¹¹⁶Sn ADs are reasonably reproduced within the U_eff without any additional adjustments over the wide energy range of this study from ~ 23 to 196 MeV. Both methods clearly show the growth in the influence of coupling to the breakup channel as a function of an increase in deuteron energy. The findings of this study provide evidence supporting the use of the U_eff to describe elastic angular distribution (AD) data across a wide range of energies.
