External links modified

Hello fellow Wikipedians,

I have just modified 2 external links on Isotopes of niobium. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

• Added archive https://web.archive.org/web/20080923135135/http://www.nndc.bnl.gov/amdc/nubase/Nubase2003.pdf to http://www.nndc.bnl.gov/amdc/nubase/Nubase2003.pdf

Evident table error

According to the table 109Nb has two decay branches representing 69+69=138% of the total number of decays.150.227.15.253 (talk) 14:07, 11 February 2022 (UTC)

Does ⁹²Nb occur in trace amount?

If so, this should be indicated in the table. 2A04:CEC0:1011:B1F1:C5E3:F416:5CD7:1B03 (talk) 23:22, 13 November 2023 (UTC)

This is already settled. Note that "trace" is also what is written in the page p-nuclei. 14.52.231.91 (talk) 00:26, 19 August 2024 (UTC)

⁹²Nb actually can only undergo EC

I mean that positron emission is (almost) impossible. From here, we know that the maximum beta plus energy of ⁹²Nb is 2005.9 keV, but the spin of ⁹²Nb is 7⁺, so beta plus decay would be impossible except to the 4⁺ state of ⁹²Zr with an energy of 1495.46 keV above the ground state. The decay schema of ⁹²Nb confirms this. — Preceding unsigned comment added by 103.166.228.86 (talk) 13:05, 9 September 2024 (UTC)
