Alpha decay to OE81Tl205
[edit]If an atom of OE83Bi209 decays by alpha particle emission to an atom of OE81Tl205, then when and how does it get rid of the 2 extra electrons and how much lost kinetic energy is involved in that?WFPM (talk) 07:16, 18 April 2011 (UTC)
Stability trend lines at 81 Tl Thallium
[edit]81Tl Thallium has 2 stable isotopes. There's OE81Tl205 with 70% constituency and OE81Tl203 with 30%. This indicates a bias in favor of the higher number of extra neutrons (43) for OE81Ti205 than the (41) for OE81Tl203. The 2 stability trend lines passing through these Elements are A = 3Z - 38 for OE81Tl205 and A = 3Z - 40 for OE81Tl203. Both of these trend lines extend through 82Pb lead and the A = 3Z - 40 line extends to OE83Bi209, and then both lines abruptly run into the instability occurrence of Alpha particle emission. This is curious in the range of the elements up to 86Rn Radon, because both lines continue to have long half-life isotopes up to 94Pu Plutonium and 96Cm Curium.WFPM (talk) 20:37, 28 February 2012 (UTC)
Question
[edit]Is Thallium-208 beta emitter or gamma? This article lists beta. But http://wiki.riteme.site/wiki/Thorium_fuel_cycle says "Uranium-232 has a relatively short half-life (68.9 years), and some decay products emit high energy gamma radiation, such as 224Rn, 212Bi and particularly 208Tl. — Preceding unsigned comment added by George_lerner (talk • contribs)
Beta decay is frequently accompanied by gamma radiation as the initial decay goes in to excited states of the daughter nuclide which then emit prompt gamma rays to get to the ground state. The spin of Tl-208 is 5 so it probably decays mostly in to spin 5, 4 and 6 excited states of Pb-208. These would probably emit two or more gamma rays on the way to the spin 0 ground state of Pb-208. 99.32.173.161 (talk) 21:36, 1 August 2014 (UTC)

"Longest"??
[edit]"207Tl, with a half-life of 4.77 minutes, has the longest half-life of naturally occurring radioisotopes." It's obviously not the longest. Probably it's the shortest, but I don't know that for sure. 98.51.99.230 (talk) 06:59, 8 January 2022 (UTC)
- Thallium-207 is the longest-lived thallium isotope produced in the decay chains of primordial thorium (232
Th
) and uranium (235
U
and 238
U
). Certainly, longer-lived thallium isotopes exist, but they don't exist in nature – are you perhaps thinking of something else? ComplexRational (talk) 15:12, 8 January 2022 (UTC)
207Tl is the heaviest known alpha stable nuclide
[edit]206Tl and 207Tl are the only alpha stable isotopes of thallium. The energy difference is respectively 282.2 keV and 772.4 keV. 129.104.241.214 (talk) 12:10, 28 November 2023 (UTC)
