† metabolon Physics. Obs.|mɛˈtæbəlɒn|
[ad. Gr. µεταβόλον, neut. of µεταβόλος changeable, f. µεταβάλλειν to change.]
A radioactive atom produced in the process of radioactive disintegration.
1903Rutherford & Soddy in Phil Mag. V. 586 At each stage [of disintegration] one or more α ‘rays’ are projected, until the last stages are reached, when the β ‘ray’ or electron is expelled. It seems advisable to possess a special name for these now numerous atom-fragments, or new atoms, which result from the original atom after the ray has been expelled, and which remain in existence only a limited time... We would..suggest the term metabolon for this purpose. 1904E. Rutherford Radio-Activity x. 324 The various metabolons from the radio-elements are distinguished from ordinary matter by their great instability and consequently rapid rate of change. |
