Mechanical oscillations cause iron to become transparent to gamma rays Iron nuclei can be made transparent to gamma rays that they would normally absorb using a new technique called “acoustically induced transparency” (AIT). This feat was achieved by physicists in the US and Russia, who vibrated an iron Mössbauer absorber using a piezoelectric transducer. The researchers believe the effect could help to control the emission of radiation from nuclei, allowing more accurate atomic clocks and other quantum optical devices to be created. The technique could even be used to slow the passage of gamma rays through a material.
Like every effect which affects behaviour of atom nuclei at much higher energy density scales this finding is of potential importance for LENR and overunity generation. See also:
