Mössbauer: recoil-free nuclear gamma resonance in iridium-191

What changed

A new path to sharp nuclear gamma resonance in solids was experimentally identified.

Scientific scope

Sole-author 1958 German paper; thesis, confirmations and later spectroscopy applications separate.

Evidence

The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is the exact 1958 German-language Zeitschrift für Physik paper. The thesis, subsequent confirmation, the named effect’s later spectroscopy applications and related neutron-resonance theory remain separate.
