"Enduring excited state" and "daughter decay products"

Hi Sbharris, in relation to your recent edit, I'd like to request clarification on a couple of points:

What is your concern with the phrase "enduring excited state"? To my mind, it is enduring by the standards of excited states, not just by the standards of gamma decay. Or you could think about it as enduring by the standards of nuclear isomers, which is really the only way you get gamma decay anyway. I like to minimize the complexity of the introductory sentence of major sections, so I'd like to reduce the number of words here if we can.
Why is "daughter decay product(s)" a better term than "daughter elements"? I'm very used to hearing the latter, but this is my first encounter with the former.

Cyclotron Bombardment of Molybdenum -- With What?

The article states, "Technetium-99m was discovered as a product of cyclotron bombardment of molybdenum." However, it doesn't state what the molybdenum was bombarded with. Electrons, maybe? Anyone know how to find out for sure? Thanks. Art Smart ^Chart/Heart 16:14, 13 April 2023 (UTC)[reply]

My guess is since molybdenum's atomic number is 42 and technetium's is 43, it must be by positron bombardment, turning a neutron into a proton. That would keep the atomic weight 99, but increase the atomic number by 1. Does that make sense? Thanks again. Art Smart ^Chart/Heart 16:34, 13 April 2023 (UTC)[reply]
