Range of data values

[edit]

The range of data values for the even Z isotope 52Te Tellurium is from atomic mass value 105 (with 3 extra neutrons to atomic mass value 142 with 38 extra neutrons or 38 atomic mass value numbers. The range of the stable isotope mass numbers is from EE52Te120 with 16 extra neutrons through EE52Te130 with 26 extra neutrons. Of the 11 isotope locations within that span, all 6 of the EE isotopes are stable plus 2 of the 5 EO isotopes. The decay modes outside of that range of isotopes are by B- emission for the heavier isotopes and by B+ emission and/or electron capture for isotopes down to the mass value 110, and a hypothesized alpha emission or B+ emission below that. The central isotope stability trend that runs through the monoisotopic element OE53I127 (with 21 extra neutrons). has the formula A = 3Z - 32. This line extends to the (almost 100%) isotope OE57La139 with only 25 extra neutrons. The range of alpha emission occurrence by this element is thus well beyond its natural range of occurrence, and may be related to nuclear fission processes.WFPM (talk) 02:05, 30 March 2012 (UTC) The reported halflife value of EO52Te113 (with 9 extra neutrons) is inconsistent (too low) in comparison with the halflife values of the adjacent EO isotopes.WFPM (talk) 02:11, 30 March 2012 (UTC)[reply]

Te-108 decay product error?

[edit]

Can someone correct the table. The first instance of B+, p decay shows the wrong result, or maybe the decay is written incorrectly.--KitemanSA (talk) 04:10, 8 September 2012 (UTC)[reply]

Looks like this needs to go to Sn-107. as here. If it loses a proton it certainly can't keep the same mass number, right? I'll fix it preliminarily. SBHarris 04:41, 8 September 2012 (UTC)[reply]
KitemanSA and Sbharris are correct, but the final element of the Te-108 beta-delayed proton emission is Sn-107. The positron (e+) emission carries away one positive charge. The subsequent proton emission carries away another positive charge and one nucleon. Thus, the nucleons are reduced by one and the positive charge reduced by two, yielding Sn-107, which has 50 bound protons versus Te-108's 52 bound protons. See also:
Sbharris's 7-December-2012 edit corrected the nucleon number, but forgot to change the element from Antimony (Sb) to Tin (Sn). I will correct this momentarily. OhioFred (talk) 18:01, 9 January 2013 (UTC)[reply]

T-130 half-life

[edit]

Looks more complicated than the article suggests, apparently there are two groups of measurements with conflicting results, see this paper for example. How to include that in the article? --mfb (talk) 12:23, 22 January 2015 (UTC)[reply]

Te-121 half-life?

[edit]

Main isotopes of tellurium table in top right says "16.78 d" but list of isotopes table says "19.16(5) d", with no references for either.

From the NuDat website [[1]] the half life is 19.17 d but an old book I have, Decay Schemes of Radioactive Nuclei (BS Dzhelepov & LK Peker, Pergamon Press, 1961) says 17 d. Any thoughts on a definitive answer?

Expected decay of 123Te

[edit]

Here the 123Te partial half-life for β+/EC is theoretically predicted as (4.2 – 7.2) × 1019 years. Double sharp (talk) 08:36, 13 December 2023 (UTC)[reply]

Non-alpha-stables isotopes of Te

[edit]

The non-alpha-stable isotopes of Te are 104Te through 119Te. A near miss to the beta-stability line! 129.104.241.214 (talk) 16:12, 3 February 2024 (UTC)[reply]

alpha half-life of 104Te

[edit]

It is possible that 104Te has an alpha decay half-life at the order of ps. In any case, it seems that 104Te is the only nuclide yet known to have an alpha half-life between 8Be (81.9 as) and 219Pa (53 ns). 129.104.241.193 (talk) 22:14, 5 May 2024 (UTC)[reply]
