Abstract
The energies of near-threshold states of the 
Be nucleus and their widths with respect to real and virtual decays into neutron channels are studied for the first time within the ab initio approach developed by the present authors on the basis of the cluster channel orthogonalized functions method. The results obtained for these quantities are found to be in satisfactory agreement with experimental data, whereby good prospects of application of this and other ab initio approaches to describing processes induced by neutron interaction with light atomic nuclei is demonstrated
