It's not easy to imagine how high the frequency of a high-energy gamma ray is. During the time it takes for its wave to go through one cycle, a gamma-ray wave traveling at the speed of light will ...

PGAA is particularly valuable as a non-destructive nuclear method in the measurement of elements that do not form neutron capture products with delayed gamma-ray emissions. Inaccurate and incomplete ...
