Barium 112?

[edit]

The article on isotopes of xenon briefly mentions barium-112 as the "heaviest nuclide with equal numbers of protons and neutrons". It isn't in the Ba article; maybe it was discovered recently, or maybe it isn't confirmed and the article on isotopes of Xe needs fixing. Can someone fix this? It's beyond my level of expertise.

I found a reference on it, but it requires subscription to access: https://link.springer.com/chapter/10.1007/978-3-540-70609-0_115. –LaundryPizza03 (d) 23:51, 31 May 2018 (UTC)[reply]

Possible alpha decay of 140Ba

When NUBASE2020 lists only an upper limit for the intensity of a decay mode, has the process been observed?

[edit]

NUBASE2020 says 12C<0.0034 for 114Ba.

In the explanation there is a sentence "α=? means that the α-decay is observed, but its intensity is not experimentally known". It does not explain for "(decay mode)<(upper limit)". 129.104.241.214 (talk) 14:38, 24 February 2024 (UTC)[reply]

why isn't 140Ba listed as a main isotope?

[edit]

It has the longest half-life among the unstable isotopes of barium as fission products! 14.52.231.91 (talk) 07:56, 15 August 2024 (UTC)[reply]
