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)

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 the cases of ¹⁶³Dy and ²⁰⁵Tl, I can't find any? 129.104.241.214 (talk) 23:59, 9 October 2023 (UTC)

Double beta decay of ¹⁹⁰Pt?

The Wikipedia page Double beta decay states that ¹⁹⁰Pt is also theorized to undergo β+β+ decay. 129.104.241.214 (talk) 02:25, 10 October 2023 (UTC)

Possible alpha decay of ^{187,189,191,192,193,198}Pt

According to [1], several isotopes of platinum should have a partial alpha decay half-life at the order of:

¹⁸⁷Pt: 10² years;

¹⁸⁹Pt: 10⁷ years;

¹⁹¹Pt: 10¹³ years;

¹⁹²Pt: 10²² years (according to [2]);

¹⁹³Pt: 10²⁵ years (and possibly as much long as 10³² years given the trend shown in the link above).

¹⁹⁸Pt, having such a high N/Z ratio (second only to the alpha stable nuclide ²⁰⁴Hg among the stable nuclides), has a very low alpha decay energy of 0.11 MeV (higher only than that of ¹⁵⁵Gd, ¹⁶²Dy and ¹⁷⁰Er among the stable nuclides), so alpha decay may be possible but with a half-life long beyond imagination (at the order of 10³²² years as shown in the link above, second only to 10⁴⁰⁸ years for ¹⁷⁰Er among the stable nuclides).
