  An $\left( n+1\right) -$D coefficient inverse problem for the radiative
stationary transport equation is considered for the first time. A globally
convergent so-called convexification numerical \ method is developed and its
convergence analysis is provided. The analysis is based on a Carleman estimate.
In particular, convergence analysis implies a certain uniqueness theorem.
Extensive numerical studies in the 2-D case are presented.
