I am more platonically interested in rocks, but these seminars are always great so I'll watch the video anyway.

* NOT * Rockstar dating !!! 😂😂

[@ghlscitel6714]

Accelerator mass spectrometry is much more sensitive than chemical separation and nuclear spectroscopy.

[@victordonchenko4837]

I wouldn't recommend dating rocks myself. They tend to be pretty bad at communication.

[@SimonsNuclearchemistry]

They can also Break your heart, if used correctly :D

Perfekt :D

I think 176Lu is used in dating meteorites if I’m correct.

I loved this. I would love to learn about how FE fusion works

Unrelated to the video, but I noticed on wikipedia it states that Y90 has a 0.01% chance of emitting a 1.7 MeV gamma ray during its decay, but every other source I found says it is a pure beta emitter. Have you ever detected this photon with your equipment?

[@SimonsNuclearchemistry]

Never bothered with measuring Y-90 for long time. Looking at the Isotope Browser App (best source for these types of information. [App/Playstore] alongside the NDS web) Y-90 has a 2,1MeV Gamma line but with 0,0000014% so practically a pure Beta emiter for all normal circumstances.

@@SimonsNuclearchemistry awesome, thank you
