It is well known that the lattice structure of a scintillating crystal can influence the development of the electromagnetic processes inside it. For electron and photon beams aligned with the symmetry axis of a crystal, if the strong field condition is satisfied, a reduction of the radiation length X$_0$ is expected. However, these effects have been experimentally observed only in the last few...
