                         The longitudinal magnetoresistance Rxx exhibits pronounced 
                         Shubnikovde Haas (SdH) oscillation at 4.2 K that persists up to 80 
                         K. The second derivative (\−d2Rxx/dB2 ) versus 1/B curve 
                         shows a clear beating pattern and the fast Fourier-transform 
                         analysis reveals that the SdH oscillations are composed of two 
                         close frequencies. As SnTe has elongated bulk Fermi ellipsoids, 
                         the 1/ cos \θ dependence obtained in the angular evolution 
                         of both SdH frequencies is not sufficient to assure conduction via 
                         surface states. The Lifshitz-Kosevich fitting of the Rxx 
                         oscillatory component confirms the two frequencies and enables us 
                         to extract the Berry phase of the charge carriers. The most likely 
                         scenario obtained from our analysis is that the beating pattern of 
                         these quantum oscillations originates from the Rashba splitting of 
                         the bulk longitudinal ellipsoid in SnTe.",
