beta-plus decay
beta-plus decay

gamma decay
gamma decay

alpha decay

Answer 1

None of the listed types of decay (beta-minus decay, beta-plus decay, gamma decay, or alpha decay) are forms of nuclear fission.

Nuclear fission specifically refers to the process where a heavy nucleus splits into two or more smaller nuclei, along with the release of energy and additional neutrons. This process is typically associated with heavy isotopes such as uranium-235 or plutonium-239.

Here's a brief description of the types of decay mentioned:

- **Beta-minus decay**: A neutron in the nucleus is converted into a proton, emitting an electron (beta particle) and an antineutrino.

- **Beta-plus decay**: A proton is converted into a neutron, emitting a positron (beta particle) and a neutrino.

- **Gamma decay**: An excited nucleus releases energy in the form of gamma radiation, without changing the number of protons or neutrons in the nucleus.

- **Alpha decay**: An unstable nucleus emits an alpha particle (consisting of 2 protons and 2 neutrons), resulting in a new nucleus with a lower atomic number.

In conclusion, the correct answer is that none of the above are forms of nuclear fission. Nuclear fission is a distinct process involving the splitting of heavy nuclei.
