Talk:Isotopes of platinum

Column

There is a column on the right entitled "Range of natural variation" with no items in it. This is idiotic. — Preceding unsigned comment added by 92.26.7.176 (talk) 13:06, 18 February 2013 (UTC)

In the article Isotopes of copper, some numbers do appear in the column on the right, for the two stable isotopes of copper. — Preceding unsigned comment added by 92.27.109.117 (talk) 11:32, 19 February 2013 (UTC)

The only beta-stable nuclide of odd mass number with N/Z = 1.5

¹⁹⁵Pt is the only beta-stable nuclide with odd mass number such that N:Z = 3:2. ⁵ⁿ_2nX is beta-stable for n = 1, 26, even numbers from 30 to 46 and 39 (not primordial for n = 1 or even numbers from 42 to 46). Cristiano Toàn (talk) 08:32, 28 February 2024 (UTC)For even n from 36 to 40 these nuclides are also double bete-stable

Also for 42 and 44 :) 129.104.241.242 (talk) 02:38, 5 May 2024 (UTC)

Bound-state β− decay of ¹⁹⁵Pt: reference required?

Could anyone please give some reference of the bound-state β− decay of ¹⁹⁵Pt to ¹⁹⁵Au, of which, unlike in the cases of ¹⁶³Dy and ²⁰⁵Tl, I can't find any? 129.104.241.214 (talk) 23:59, 9 October 2023 (UTC)

Removed. –LaundryPizza03 (dc̄) 14:12, 23 December 2023 (UTC)

Half-life of ¹⁹⁰Pt in dispute

[1] proposes a half-life of 4.97(16)×10¹¹ years, 4.49(5)×10¹¹ years in [2], 3.9(3)×10¹¹ years in [3] and 3.7(3)×10¹¹ years years in [4]. Note that a precise determination of half-life of ¹⁹⁰Pt is essential in radioisotopic age determination of some ores and meteorites. 129.104.241.214 (talk) 13:01, 23 December 2023 (UTC)

NUBASE2020 lists a half-life of 483(3) Gy, so we will go with that one. –LaundryPizza03 (dc̄) 13:16, 23 December 2023 (UTC)

"The Pt–Os system has seen only limited application as the radioactive contributions to ¹⁸⁶Os are, at best, very small. For the full utility of this system to be realized, better isotope ratio precisions than currently possible are needed." See page 167 of this book. 14.52.231.91 (talk) 06:49, 27 August 2024 (UTC)

NUBASE2020 is the most recent source, so I am still sticking with it. –LaundryPizza03 (dc̄) 02:17, 28 August 2024 (UTC)
