Mössbauer resonance on 119Sn

Description

Mössbauer source active part is based on calcium stannate [CaSnO3] matrix synthesized from high specific activity (> 300 mCi/g) 119mSn radionuclide. Active part is placed into titanium alloy holder with brazed beryllium window and sealed with laser welding.
