Abstract:
We investigate the Coulomb breakup of the 11 Be halo nuclei on a lead target within non-perturbative
time-dependent approach in a wide range of beam energy (5–70 MeV/nucleon) including the low-lying
resonances in different partial and spin states of 11 Be. We have found considerable contribution of the
low-lying resonances ( 5/2
+ , 3/2
− and 3/2
+ ) to the breakup cross section of 11 Be. The obtained
results are in good agreement with existing experimental data at 69 MeV/nucleon. The developed
computational scheme opens new possibilities in investigation of Coulomb, as well as nuclear, breakup
of other halo nuclei on heavy, as well as, light targets.
