21. Rubach and drummer Thomas Nack instead decided to leave Gamma Ray . 22. Such loss of energy causes gamma ray resonance absorption to fail. 23. The gamma rays emitted from the sample's elements provide a kind of fingerprint. 24. Gamma rays are extremely high-frequency radiation at wavelengths shorter than X-rays.25. Early speed metal bands include Gamma Ray , and gained international recognition. 26. Dicke narrowing is analogous to the M�ssbauer effect for gamma rays . 27. What material is used to design lenses for gamma ray photography? 28. Gamma rays are emitted by atomic nuclei in some radioactive disintegrations.29. Labov said as he displayed the Ultra-High Resolution Gamma Ray and Neutron Spectrometers. 30. Gamma rays are approximately 50 % of the total energy output.
