How is cluster decay different from spontaneous fission? --Smack (talk) 02:47, 25 Jun 2005 (UTC)
- SF happens as fission, where the daughter products are fairly random. You will never know if any single atom will decay into Tc-100 and Sb-124 or something else. In cluster decay there is always the same particle emitted. --metta, The Sunborn 18:28, 25 Jun 2005 (UTC)
Could someone add a definition for "decay percentage"?
Barium-114
Although I found some references suggesting that 114Ba might cluster-decay, subsequent studies seem to rule it out. See, for example, [1] or [2]. I've commented it out of the table. -- Xerxes (talk) 22:03, 21 April 2008 (UTC)
OE91Pa231?
A cluster emission decay mode is not shown in my 15th edition isotopes chart. And other than that, the rest of the emitted nuclides are noted to be of even numbered element nuclei with possibly an odd number of neutrons. This brings up the possibility that the emitted particle is that of a structure that is an accumulation of a (2Z)times an integer nuclide which might be sheared off from the top of the original nucleus. This would be an indication of the existence of a shear strength fault in the structure due to the nature of their physical construction properties. This possibility is not apparent under the assumption of a spherical shape for the parent nucleus. However if the shape of the parent nucleus were 4 sided the possibility of a stressed nuclear corner condition becomes apparent.WFPM (talk) 18:28, 1 December 2012 (UTC)
"24Ne" CD as decay mode - full set
In current text:
Penetrability theory predicted eight decay modes: 14C, 24Ne, 28Mg, 32,34Si, 46Ar, and 48,50Ca from the following parent nuclei: 222,224Ra, 230,232Th, 236,238U, 244,246Pu, 248,250Cm, 250,252Cf, 252,254Fm, and 252,254No.
However, {{NUBASE2020}} has a different set (defined as "24Ne = heavy cluster decay"). Below is a table to gather & hunt the complete set. Technically, I am working in {{Isotopes/decay-mode/overview}} (content documentation), and this tech set. -DePiep (talk) 06:48, 11 February 2023 (UTC)

- The explanation re
34Si, 46Ar, 48Ca, and 50Ca is that those decay modes were predicted here, but have never been seen yet. Double sharp (talk) 15:21, 11 February 2023 (UTC)
