In physics, disintegration or splitting of an atom.
The act of dividing into two or more parts.
Splitting, as in the asexual formation of new bacterial or protozoan cells or in the splitting of an atomic nucleus, with the release of energy.
A method of asexual reproduction in which the body of a protozoan or bacterium splits into two equal parts (binary fission), as in the amebas, or more than two equal parts {multiple fission), for example sporozoite formation in the malarial parasite. The resulting products of fission eventually grow into complete organisms.
