Lose the column "decay energy"[edit]
The list doesn't have "decay energy"! — Preceding unsigned comment added by 59.126.202.81 (talk) 16:03, 22 July 2012 (UTC)

Possible alpha decay of several isotopes of erbium[edit]
According to [1], several isotopes of erbium should have a partial alpha decay half-life at the order of:
149Er (N = 81): 1019 years;
150Er (N = 82): 1016 years;
151Er (N = 83): 105 years;
157Er (N = 89): 106 years;
158Er (N = 90): 1011 years (note that the alpha decay energy is only 2.67 MeV, which is lower than 2.95 MeV of its alpha product 154Dy and 2.81 MeV of its double alpha product 150Gd, and not much higher then 2.53 MeV of its triple alpha product 146Sm), meaning that the alpha-decay probability is only at the order of 10-13%.
Among the 26 isomers of erbium, only 4 show decay mode other than isomer transition?[edit]
This is amazing. There are 26 isomers listed, and the sole decay mode is isomer transition for all of them except 145mEr, 147mEr, 149m1Er and 151m1Er. 129.104.241.214 (talk) 03:48, 3 December 2023 (UTC)
Possible double beta decay of 164Er[edit]
164Er has a theoretical double beta decay energy of 23.723 keV, which is lowest double beta decay energy I can recall. Assuming that logT2β = A logQ2β + B and using the trend shown in [2], the double beta half-life 164Er should be at the order of 1037 years. It is likely that its alpha decay is not ignorable compared to double beta decay: [3] gives the theoretical half-life of double beta decay at the order of 1040 years. 129.104.241.214 (talk) 11:21, 29 January 2024 (UTC)
- Can you calculate the theoretical half-life of double beta decay of Zinc-64 & Zinc-70 Cristiano Toàn (talk) 10:53, 2 February 2024 (UTC)
- https://doi.org/10.1016/j.nuclphysa.2023.122628 gives that the double β- half-life 70Zn should be around 1.050×1023 years. As for 64Zn, there are fewer theories available for double EC, and I could not find any explicit prediction (but https://doi.org/10.3390/universe10020098 should be useful, though). 129.104.241.193 (talk) 21:10, 28 April 2024 (UTC)
