摘要：
Experimental results reflect a linear increase of the recoilless fraction and a linear decrease of the electron density at the tin nuclei of SnTe with increasing pressure to 16 kbar. Beginning with 16 kbar the appearance of the high pressure phase is observed, the recoilless fraction of which is greater and the electron density at the tin nuclei is less than the low pressure phase ones. For powdered and single crystal specimens the phase transition is accompanied by a large two‐phase region. The result of the recoilless fraction change are used for the calculation of the phase‐transition heat and the slope of the equilibrium line. Copyright © 1979 WILEY‐VCH Verlag GmbH & Co. KGaA
