Talk:Beta-decay stable isobars
|WikiProject Physics||(Rated List-class, Low-importance)|
I stopped transforming the list of beta-stable nuclides because I first like to hear other people oppinion to this kind of presentation and I'm not quite lucky with my form. Else I type in this table and then I must layout it completely different, because others have better ideas.
At the moment, it is unclear to people who do not know the subject, what this is about! It would very much help if you put explanation in along with the table you are presenting. Quantpole (talk) 22:58, 18 June 2009 (UTC)
Thanks for your helpful want-to-be hand. :) I wrote just a very bad introduction, but hopefully give the most important informations. Regards. —Preceding unsigned comment added by Achim1999 (talk • contribs) 11:31, 19 June 2009 (UTC)
For current bad reasons: I just was forced two times bei Abce2 and previous by L... (see history of the article-page) to restore the page main contens because they simple deleted most of information I added. If such behaviour stays I will no longer build up this page! Or you must give me exclusive write-acces to prevent such vandalism. Regards! —Preceding unsigned comment added by Achim1999 (talk • contribs) 14:17, 19 June 2009 (UTC)
Known Line of beta-stability finally converted completely into list of nuclides. :) Better to replace (@) in this list resp. table by colored nuclide-symbols to get this table a bit narrower? Achim1999 (talk) 14:07, 21 June 2009 (UTC)
Decays contrary to table in this article?
|Decaying nuclide||You list as stable||You list as unstable|
|17 Chlorine-36||2% to Sulfur-36||98% to Argon-36|
|19 Potassium-40||11.2% to Argon-40||89% to Calcium-40|
|47 Silver-108||0% to Palladium-108||100% to Cadmium-108|
|61 Promethium-146||37% to Samarium-146||63% to Neodymium-146|
In these 4 rows, what you have marked as the most beta-stable isobar of that mass, is different from what you would expect based on the direction of beta decay of adjacent isobars. --JWB (talk) 19:53, 6 August 2009 (UTC)
These 4 rows are yours! They are not from the article (-- I wonder about the use of your first column in this relation). I suggest you first read CAREFULLY what is stated in the article. :) E.g.: It is stated that for A=36 there are 2 beta-stable nuclides, namely 36S and 36Ar. Moreover the last is in italic because it may transform with double-beta decay or double e–-capture into sulfur-36. BTW: Your wording "most beta-stable" seems to be your invention. :) Regards, Achim1999 (talk) 21:35, 6 August 2009 (UTC)
Is "Beta-decay stable" from a source? I see 461 Google hits but they appear to be Wikipedia mirrors. If the term is your own, see WP:Neologism.
I can think of several possible meanings for "beta-decay stable":
1) Not observed to beta decay
2) Not predicted to beta decay by specific theory
3) Lowest-mass isobar for this mass number (this is what you seem to be using)
4) Direction of beta decays of other isobars of this mass number all point towards this isobar, i.e. lower-Z isobars beta-minus decay and higher-Z isobars beta-plus decay or electron capture. (this is what I used in my chart cited above)
If you are going to stick to only your definition, it would be clearer to call it something like List of lightest isobars by mass number.
If you are going to stick to a term like "beta-decay stable", you should discuss the possible meanings of the term, since people may assume various ones.
Also, the fact that 3) and 4) are opposite for the 4 cases above is interesting and would be a good point to discuss in this or another Wikipedia article. I do not have an explanation for this, do you?
"beta-decay stable" seems to be a short-hand for "stable against beta-decay", i.e. unable to decay by (simple) beta(+/-) -decay. —Preceding unsigned comment added by 188.8.131.52 (talk) 21:21, 9 August 2009 (UTC)

I would prefer something more recent, though. (Fairly obviously, all these nuclei must undergo α decay or spontaneous fission. Decay modes are from , correcting the original old Russian source if necessary. Unfortunately, that chart of predictions stops at N = 189.) Double sharp (talk) 09:17, 7 November 2016 (UTC)
- It might be salutary to remark that despite the great difficulties of getting enough neutrons into superheavy nuclides via fusion-evaporation reactions, we have somehow managed to heroically follow the line of beta stability until Ds, element 110. (We know of 262No, 266Lr, 270Rf, 270Db, 271Sg, 278Bh, 277Hs, 282Mt, and 280Ds.) Double sharp (talk) 13:58, 11 April 2017 (UTC)
