Possible double beta minus decay of 254Cf and 256Cf
254Cf and 256Cf are potentially capable of double beta minus decay, although the estimated half-life should be very long. 129.104.241.214 (talk) 11:35, 28 November 2023 (UTC)

Wikicode
In the table of isotopes, i removed the wikicode "nbsp" (no-break space) from between some combinations of number and unit (i am preceding cautiously to make sure i do not create awkward line-breaks). I feel that the wikicode "nbsp" looks ugly (wikicode, i think, should be concise), and is unnecessary when there is unlikely to be a line-break anyway; such as at or near the beginning of a line.

Theoretic alpha half-life of 256Cf
The nuclide 256Cf is the heaviest beta-stable isotope of californium (possibly also 258Cf, but probably not 260Cf), and is one of the two isotopes (254 and 256) whose stability is greatly reduced by SF decay. The predicted alpha partial half-life is very long, one or two orders of magnitude longer than that of the most stable isotope of californium, 251Cf. This is consistent with our intuition that more neutron-rich isotopes are usually more stable with respect to alpha decay (although for curium, it is the almost-beta-stable 247Cm that is the most stable isotope rather than the heaviest beta-stable 248Cm).

256Cf is the nuclide with the highest N/Z ratio among known nuclides with Z≥95, and is the most neutron-rich among known beta-stable nuclides. 129.104.241.242 (talk) 03:55, 5 May 2024 (UTC)
