摘要: The Mossbauer effect of the 23.8 keV 119Sn and 26.8 129I transitions has been studied in SnI4 crystals. From temperature dependence recoilless fraction tin iodine experiments, two significantly different characteristic temperatures have found, namely 166°K for Sn resonance 85°K I resonance. intensities peaks spectrum, Gol'danskii calculated. quadrupole‐coupling isomer‐shift measurements experiments bond structure Sn–I is derived.
