| The neutron bombardment transforms certain isotopes of the elements into radioactive species which then emit gamma rays. |
| High-frequency energy, such as X rays, gamma rays, and cosmic rays, occupies the other end of the spectrum. |
| Unlike in the earlier experiments, the team recorded gamma rays, a revealing product of fusion reactions. |
| Just as an excited atom can dispose of its excess energy by emitting x rays, an excited nucleus can emit gamma rays. |
| After a time the gamma rays are counted by gamma ray sensitive spectrometers. |
| The frequency of gamma rays is far too high and that of radio waves is far too low to interact with these kinds of vibrations. |
