Internal conversion is possible whenever gamma decay is possible, except in the case where the atom is fully ionised.
12.
For example, has a spin of " 9 and must gamma decay to with a spin of + 1.
13.
In gamma decay, a nucleus decays from an excited state into a lower energy state, by emitting a gamma ray.
14.
Neutron sources in which beryllium is bombarded with gamma rays from a gamma decay radioisotope, are also used to produce laboratory neutrons.
15.
Similarly, has a spin of-1 / 2 and must gamma decay to with a spin of + 9 / 2.
16.
Natural sources of gamma rays on Earth are observed in the gamma decay of radionuclides and secondary radiation from atmospheric interactions with cosmic ray particles.
17.
These usually immediately undergo gamma decay but a small fraction of them are excited enough to be able to decay by emitting a neutron in addition.
18.
The multipole expansion of the electromagnetic field finds application in a number of problems involving spherical symmetry, for example antennae radiation patterns, or nuclear gamma decay.
19.
The decay of an atomic nucleus from a high energy state to a lower energy state, a process called " gamma decay ", produces gamma radiation.
20.
Nuclear isomers owe their long half lives to the fact that their gamma decay is " forbidden " due to a large change in nuclear spin needed to emit a gamma.
