Nuclear isomer decay is another way of getting energy out of a nucleus. A nuclear isomer is excited state of a nucleus where it is spinning very fast. X-rays can trigger the release of the energy. Some isomers have very long half-lives and are naturally occurring. It's quite of bit of energy, but not as much as fission, and it's never been proven practical.
Antimatter annihilation completely converts the mass of both to energy (gamma rays). This is not fission, which converts only a few percent of the mass. However, there is no known natural source of antimatter in significant quantities, so it must be manufactured at greater energy cost that it can release. It would therefore be an energy carrier - fuel for space ship.
Of course, there's the old standby oxidation. A carbon atom combining with two oxygen atoms releases practical quantities of energy. Unfortunately, it fills the atmosphere with carbon dioxide, causing global warming, if used to excess.

is annihilation really a type of fission? Fission is the splitting of the nucleus into small parts. At the end of the antimatter reaction no parts are left!

By electronic transition. When an electron goes from a higher energy level to a lower energy level energy is given off in the form of light.

Excitation. As in putting electricity through a neon sign to get the light.
*annihilation the same as fission.

Yeah.. by annihilation... use an anti-atom.. or an atom made from the anti-particle equivalents of this atom.. and let them meet...
They annihilate each other, and give out an burst of energy...
