The last beta-stable nuclide of odd mass number with N/Z = 4/3[edit]

¹⁵⁴Dy is the last beta-nuclide such that N:Z = 4:3. ⁷ⁿ_3nX is beta stable for n = 1, even numbers from 10 to 18 and 22 (not primordial for n = 22). Cristiano Toàn (talk) 01:06, 23 February 2024 (UTC) For n=10 we have ⁷⁰Zn, this nuclide is predicted to undergo double beta decay to ⁷⁰Ge For n=14 we have ⁹⁸Mo, this nuclide is predicted to undergo double beta decay to ⁹⁸Ru For n=18 we have ¹²⁶Xe, this nuclide is predicted to undergo double electron capture to ¹²⁶Te[reply]

Possible alpha decay of several isotopes of dysprosium[edit]

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

¹⁵⁶Dy: 10²⁴ years (note that the alpha decay energy is 1.7530 MeV, which is lower than 2.2044 MeV of its alpha product ¹⁵²Gd, 1.9868 MeV of its double alpha product ¹⁴⁸Sm and 1.9032 MeV of its triple alpha product ¹⁴⁴Nd). Alpha decay could be non-ignorable compared to double beta: Assuming that logT^2β = A logQ^2β + B and using the trend shown in [2], its double beta decay half-life should be at the order of 10²⁰ years;

¹⁵⁸Dy: 10⁵⁸ years (note that the alpha decay energy is 0.8737 MeV, which is lower than 0.9203 MeV of its alpha product ¹⁵⁴Gd, 1.4498 MeV of its double alpha product ¹⁵⁰Sm, 1.1824 MeV of its triple alpha product ¹⁴⁶Nd and 1.3035 MeV of its quadruple alpha product ¹⁴²Ce);

¹⁶⁰Dy: 10¹⁰⁵ years;

¹⁶¹Dy: 10¹²⁹ years;

¹⁶²Dy: 10³⁰⁴ years.

According to [3], several isotopes of dysprosium should have a partial alpha decay half-life at the order of:

¹⁴⁷Dy (N = 81): 10²³ years;

¹⁴⁸Dy (N = 82): 10²⁵ years;

¹⁴⁹Dy (N = 83): 10⁹ years;

¹⁵⁵Dy (N = 89): 10¹⁰ years (note that the alpha decay energy is 2.61 MeV, which is even slightly lower than 2.65 MeV of its alpha product ¹⁵¹Gd). 129.104.241.214 (talk) 00:41, 28 December 2023 (UTC)[reply]
