Half-life of OO75Rh180 Rhenium

The half-life of OO75Rh180 is low in comparison to the stability trend line through its immediate OO neighbors, with OO75Rh182 being 17.7 hours, OO75Rh180 reported as 2.45 minutes, and OO75Rh178 as 13.2 minutes, which distorts the OO stability trend line profile for this element.WFPM (talk) 00:36, 22 April 2013 (UTC)[reply]

Possible alpha decay of ¹⁸⁵Re

According to [1], ¹⁸⁵Re should have an alpha decay half-life at the order of 10²⁴ years. Adding one more proton would reduce alpha stability by nine orders of magnitude. 129.104.241.214 (talk) 20:22, 5 January 2024 (UTC)[reply]

Considering that this is the same order as ¹²⁸Te, perhaps rhenium has a good chance to be the next primordial radioactive element that all the pedants will mention after bismuth. (Not sure how long it would take to find that out, though.) Double sharp (talk) 09:22, 9 January 2024 (UTC)[reply]

Well I have made a calculation error: the geometric mean of the three values in the table should actually be at the order of 10²⁵ years. 129.104.65.7 (talk) 15:36, 1 February 2024 (UTC)[reply]

¹²⁸Te is a special case, not from direct measurement but geochronology. I believe from measurement by mass spectrometry of excess (stable) Xe-128 (to which Te-128 it has decayed by double beta decay) in rocks containing Te-128. It's a sort of Te/Xe dating, but using the date of the rock found by other means to inversely measure the half life of the Te-128 in it. It half-life still dispute some source list at 2.2x10²⁴ years but some list at 7.7x10²⁴ yearsCristiano Toàn (talk) 01:52, 29 January 2024 (UTC)[reply]

Cristiano Toàn (talk) 10:47, 23 January 2024 (UTC) might be measured by geochemistry method as Rhenium is siderophile element while tantalum is Litriophile element[reply]

After all, EC of ¹²³Te, many double beta decays, and alpha decays of these nuclides (from shortest to longest: ¹⁸⁷Os, ¹⁴⁹Sm, ¹⁷⁶Hf, ¹⁷⁷Hf, ¹⁴⁵Nd, ¹⁹²Pt, ¹⁷⁸Hf) still have theoretical half-lives shorter than half-life of ¹²⁸Te. 14.52.231.91 (talk) 06:35, 27 August 2024 (UTC)[reply]

It seems that there are many double beta decays (double beta minus or plus) that have half-lives between 10²¹ years and 10²³ years. 14.52.231.91 (talk) 07:11, 27 August 2024 (UTC)[reply]

Possible alpha decay of ¹⁸³Re

¹⁸³Re has slightly lower alpha-decay energy than ¹⁸⁵Re (2.12 MeV vs 2.19 MeV), so its alpha-decay half-life should be at the order of 10²⁵ years. 129.104.241.214 (talk) 21:57, 27 January 2024 (UTC)[reply]
