Investigation of low-lying resonances in breakup of halo nuclei within the time-dependent approach

We investigate the Coulomb breakup of $$^{11}$$ Be halo nuclei on a heavy target ( $$^{208}$$ Pb) from intermediate (70 MeV/nucleon) to low energies (5 within non-perturbative semiclassical and quantum-quasiclassical time-dependent approaches. The convergence computational scheme is demonstrated in this energy range including n + $$^{10}$$ low-lying resonances different partial spin states. have found considerable contribution $$5/2^{+}$$ resonance $$E_{r}$$ = 1.23 MeV) cross section at 30 MeV/nucleon lower, while higher energies, resonant states $$3/2^{-}$$ $$3/2^{+}$$ (with 2.78 3.3 make most visible contributions. obtained results are good agreement with experimental data available 69 72 MeV/nucleon. Comparison existing theoretical calculations other authors for 20 also made. developed opens new possibilities investigation Coulomb, as well nuclear, light targets.
