Talk:Isotopes of hafnium

Redudant note for Hf-182

I'm new at this editing thing so I'll just point it out in this talk page since I don't see why Hf-182 has a tag of potentially appearing in trace amounts. First of all, it isn't the only isotope that it's a theoretical decay product. Second, W-186 has a predicted alpha half life in excess of 1E50 years, much greater than its double decay half life or the half life of Hf-182. There's no way any detectable quantity of this isotope would be the result of this alpha decay. It's pretty useless to consider an occurence of less than a single atom on Earth as a trace.

Possible alpha decay of ¹⁵⁴Hf

According to [1], the alpha decay partial half-life of ¹⁵⁴Hf should be at the order of 10⁷ years, making its alpha decay possibility approximately 6.17×10^-13%. 129.104.241.214 (talk) 20:14, 5 January 2024 (UTC)

Possible observed alpha decay of ¹⁷⁶Hf, ¹⁷⁷Hf

according to [2] the projected half-life of ¹⁷⁶Hf and ¹⁷⁷Hf is about 10^20 to 10^22 years, hus their decay can be discovered by current method Cristiano Toàn (talk) 07:35, 28 January 2024 (UTC)
