Abstract The number of Moessbauer quanta from the 23.8 keV state of Sn119 in a tin metal source was measured after attenuation by a 16.1 mg/cm2 absorber of tin metal, as a function of temperature above and below the transition point of superconductivity. Source and absorber were kept at the same temperature. The data give evidence of a discontinuous change at the transition temperature: The transmitted intensity is lowered by (1,3±0.15)·10−3 in the superconducting state of source and absorber. This corresponds to an increase of the Debye-Waller-factor by about 0,4%.
