We investigate the Coulomb breakup of the 11Be 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 11Be. 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. © 2022, Eurasian Journal of Physics and Functional Materials.
