Description
We investigate the breakup of $^{11}$Be halo nuclei on a light ($^{12}$C) and heavy ($^{208}$Pb) targets from intermediate (67 MeV/nucleon) to low (5-30 MeV/nucleon) energies within non-perturbative quantum-quasiclassical approach, in which the three dimensional time-dependent Schrödinger equation for halo nucleon was integrated simultaneously with the classical Hamiltonian equations describing relative projectile-target dynamics.
The uniqueness of our calculations lies in the inclusion of low-lying resonances (3/2$^{-}$, 3/2$^{+}$ and 5/2$^{+}$) in the breakup cross section of the $^{11}$Ве nucleus. The obtained results describe well the existing experimental data and also are in comparative agreement with other existing calculations performed with alternative theoretical models at 67 MeV/nucleon and 20 MeV/nucleon. Summarizing, the developed computational scheme can potentially be useful for interpretation of low-energy experiments on studying breakup of halo nuclei.
