The change in mobility with increasing the temperature which may be due to
 the inclusion of gLO-phonon energy of 720K, is presented. In orientation of the uniaxial
 pressure X//[110]//J, g-transitions are attached in the directions [100] and [010]. The ftransitions
 are not completely removed from valleys located in the plane (100). In this
 case, there is no change in the slope of the dependence logρ vs. logT for the
 temperature range 300 to 450 K. So, no contribution of g-transitions to intervalley
 scattering occurs, while the observed is tha decisive role of f–transitions to this
 scattering.
