Abstract: Raman spectra of the MgB

_{2}

$_2$ ceramic samples were measured as a function of pressure up to 32 GPa at room temperature. The spectrum at normal conditions contains a very broad peak at

\sim 590

$\sim590 \,$ cm

^{- 1}

$^{-1}$ related to the

E_{2 g}

$E_{2g}$ phonon mode. The frequency of this mode exhibits a strong linear dependence in the pressure region from 5 to 18 GPa, whereas beyond this region the slope of the pressure-induced frequency shift is reduced by about a factor of two. The pressure dependence of the phonon mode up to

\sim 5

$\sim5 \,$ GPa exhibits a change in the slope as well as a «hysteresis» effect in the frequency vs. pressure behavior. These singularities in the

E_{2 g}

$E_{2g}$ mode behavior under pressure support the suggestion that MgB

_{2}

$_2$ may undergo a pressure-induced topological electronic transition.
