Iridium is the world's rarest metal mostly found in Ethiopia. It was also discovered to absorb gamma rays in 1961. Sunglasses containing small amount of Iridium is selling for big bucks on ebay.

If this metal is so good at absorbing harmful sun rays I wonder why it isn't used more on a wider scale. I'm sure Iridium will definitely be needed in 2012 when the solar maxium comes around.

Mössbauer was able to observe resonance in solid iridium, which raised the question of why gamma-ray resonance was possible in solids, but not in gases. Mössbauer proposed that, for the case of atoms bound into a solid, under certain circumstances a fraction of the nuclear events could occur essentially without recoil. He attributed the observed resonance to this recoil-free fraction of nuclear events.

The Mössbauer effect was one of the last major discoveries in physics to be originally reported in German language. The first report in English language was a letter describing a repetition of the experiment.[1]

The discovery was rewarded with the Nobel Prize in Physics in 1961 together with Robert Hofstadter's research of electron scattering in atomic nuclei.




The Mössbauer effect, or recoilless nuclear resonance fluorescence‎, is a physical phenomenon discovered by Rudolf Mössbauer in 1958. It involves the resonant and recoil-free emission and absorption of γ radiation by atomic nuclei bound in a solid. Its main application is in Mössbauer spectroscopy.
