process in which two nuclei collide to produce one or more nuclides

smallest amount of fissile material needed for a sustained nuclear chain reaction

one single nuclear reaction causes more subsequent nuclear reactions

form of radioactive decay found in very heavy chemical elements

material capable of sustaining a nuclear fission chain reaction

naturally occurring uranium deposit where self-sustaining nuclear chain reactions have occurred

product of nuclear fission

type of nuclear bomb that uses a small amount of fusion fuel to increase the rate, and thus yield, of a fission reaction

1938 achievement in physics

radiometric dating technique based on analyses of the damage trails, or tracks, left by fission fragments in certain uranium-bearing minerals and glasses

fission-based nuclear weapon

Photofission is a process in which a nucleus, after absorbing a gamma ray, undergoes nuclear fission and splits into two or more fragments.
