Talk:Isotopes of tantalum

message: Hey, I'd love to read more about these nuclear isomers - especially now that I know I actually own an extremely small quantity of the stuff - in capacitors, of course! I remember feeling pretty amazed when I first read about it not that long ago; even more surprised when I found out that the discovery was much longer ago (I guess it didn't make the news... ) Zaphraud (talk) 05:18, 25 March 2011 (UTC)

message: If I've calculated correctly, Tantalum-180m is also energetically capable of alpha decay into Lutetium-176, another primordial isotope. That would only require the loss of two units of spin through gamma rays. Is there a reason this is forbidden? 2600:8803:B102:F900:ECB7:DA58:A0D2:99A4 (talk) 22:54, 20 August 2023 (UTC)
replies: text: In theory, all stable nuclides with mass ≥ 142, other than 142,150Nd, 144,154Sm, 156,157,158,160Gd, 159Tb, 163,164Dy and 204Hg, are energetically allowed to undergo alpha decay. But the theory is just the theory: many of them also have much too long half-life in theory! According to , only 149Sm and 187Os have theorized half-life less than 1020 years among those that are observationally stable, so one could expect that they are the only candidates yet to be found to undergo alpha decay. As one can see, then theorized alpha decay half-life of 180mTa is at the order of 1026 years. 129.104.241.214 (talk) 22:27, 9 November 2023 (UTC)
thread_title:  Alpha decay of Tantalum-180m 

message: According to , 156Ta should have a partial alpha decay half-life at the order of 103 seconds, corresponding to a probability at the order of 0.01%.
155Ta has similar decay energy as 167Ta, so its alpha decay half-life could be at the order of 103 years, corresponding to a probability at the order of 10-12%. 129.104.241.214 (talk) 21:10, 28 January 2024 (UTC)

message: This request was placed in the article. I've moved it here because this is the place for questions/comments/etc. about the article. From User:SalvageInsaneeeee: NOTICE: Tantalum-180m is supposed to say 1.44x10^27 years, i just suck at wikitext also remove this when someone fixes my wikitext problem.   Joyous! Noise! 23:47, 24 February 2024 (UTC)
replies: text: If 180mTa has indeed that half-life then there would be almost no hope detecting the radioactivity. I would guess that this is just a prediction. 129.104.241.218 (talk) 08:38, 10 April 2024 (UTC)
