The decay products listed for Zn-65
The decay modes listed for Zn-65 in the two different tables on this page are conflicting - I couldn't tell you what it should be without some research, but I'm sure the person who manages those tables could!

(This page says decay mode for Zn-65 is both beta and gamma: https://ehs.princeton.edu/laboratory-research/radiation-safety/radioactive-materials/radioisotope-fact-sheets/zinc-65) SCPL (talk) 18:25, 6 July 2023 (UTC)


 * Good observation. The correct decay mode for 65Zn, as given in NUBASE2020, is positron emission. While this process can include gamma rays, there is no gamma decay without beta decay, as only the ground states of 65Zn and its decay product 65Cu are involved. I fixed the top-right table (Infobox zinc isotopes) to reflect the correct decay modes. Complex / Rational  20:29, 6 July 2023 (UTC)

Why is the production of 60Zn endothermic?
Mass of 4He + 56Ni = 4.002603254130 + 55.942132 = 59.944735

Mass of 60Zn = 59.941827, which is smaller? 129.104.241.214 (talk) 21:15, 25 October 2023 (UTC)
 * You are correct, it is exothermic. And adding further alphas is actually exothermic all the way to 100Sn. The problem is rather that it is not exothermic enough: the amount of energy released drops sharply after 56Ni, and addition of further alphas cannot effectively compete with photodisintegration.

Isotopes of zinc have exceptionally high beta decay energy
And also, the energy differences between the isobaric pairs 64Ni-64Zn (1095.28 keV) and 70Zn-70Ge (998.46 keV) are quite large, compared with other even-even isobaric pairs that surrounds an odd neutron number with no beta-stable isotones and an odd atomic number with two beta-stable isotopes (like 432.13 keV for 36S-36Ar); see the table of Talk:Double beta decay. 129.104.241.214 (talk) 10:03, 19 February 2024 (UTC)
