摘要：
A simple three-body oscillator cluster shell model is proposed as an approximation for wave functions of neutron-rich nuclei, having a (core + 2n) structure. The model is applied to the Li-11 nucleus. With a few free parameters the model reproduces the experimental rms matter radius of Li-11, as well as the experimental transverse momentum distribution of the Li-9 nucleus resulting from Li-11 fragmentation on a carbon target at an energy of 790 MeV/nucleon. The transverse momentum distributions of the neutrons from this reaction have also been calculated without any additional parameters. All geometric parameters of the Li-11 nucleus are also calculated within the framework of this three-body model.
