C-14 decays by emission of a beta particle (an electron).
Laser is an acronym for light amplification by stimulated emission of radiation.
He also came up with its name - an acronym for "light amplification by stimulated emission of radiation."
This quickly decays by successive emission of two beta particles to become U-234.
The gain medium is a material with properties that allow it to amplify light by stimulated emission.
However, there were also theoretical predictions from nuclear physics that bismuth-209 would decay very slowly by alpha emission.
In the t-channel, the particles exchange intermediate states by emission and absorption.
Where potential gradients are used to create excited states that decay by light emission.
Light absorbed and not lost by emission results in heating.
Uranium 238 will decay by alpha emission into thorium 234.
