At room temperature, approximately 20% of 119Sn g-decays in the BaSnO3 compound occur without recoil (Mossbauer effect). Estimate what the thickness L of the source should be so that there is no noticeable absorption of Mössbauer g quanta in it. The density of BaSnO3 is p = g/cm3, the content of the 119Sn isotope in the natural mixture is e = 8%, the energy of g-quanta is Eg = 24 keV.
