  The spectrum, partial and total decay widths of the states of the exotic 10Li
nucleus are studied in an ab initio approach. The spectrum is calculated using
No-Core Shell Model and corresponding extrapolation procedure. The calculations
use the well-proven Daejeon16 potential. The NCSM-based approach, which
includes a method for constructing the basis of functions of cluster channels
and a procedure for matching the cluster form factors obtained within this
method with the asymptotic wave functions, is applied to compute the widths of
the levels. The results obtained quite adequately reproduce the pattern given
by the most advanced experiments. Detailed predictions of the spectral
characteristics of 10Li nucleus states are given.
