Abstract
The preemission of neutrons from 11Li halo nuclei is considered. The present problems of investigation of 11Li halo nucleus structure by means of the C nn correlation function are briefly presented. The influence of the target screening on the halo neutron preemission is described. It is shown that, owing to the diminishing of the screening effect, the yield of preemission neutron pairs is expected to be much larger in the case of 12C than in the case of Si target. It is shown that a new experiment on a 12C target will allow one to solve the standing problems of C nn and to test experimentally a recent new theory of C nn.
