I wonder if a radiacode could detect a cluster emission because that would be awesome But once again great lecture

[@eucompsa]

I got through 5 years of chemistry education calling it "awww-gerr"😅 It sounds so fancy now

[@SimonsNuclearchemistry]

Yeah we also had some students presenting something about it, pronouncing it the same way ;D happens to the best^^

[@brfisher1123]

Do you have anything that can detect the low energy electron capture x-rays of potassium-40 which should be at around 3 keV? I’d like to see the detection of the 3 keV e. capture x-rays of 40K in addition to the 1.46 MeV gamma rays and the 511 keV annihilation peak.

[@SimonsNuclearchemistry]

We have a X-Ray detector, that no one really uses. That might Do the Trick^^ will try it :D

[@yaykruser]

So, did I get that right: The energy of braking radiation depends on the number of Protons/ electrons and not on the density? So lead would give higher energy braking radiation than gold even though it has a lower density?

[@SimonsNuclearchemistry]

In theory yes for charged particle radiation. But there is one factor that playes role in the practise. See that only occures if it flies near a highly charged Atom. And since Gold has a higher density, more of there breaking Events could occure. And if the Material is like 2 cm thick. That question become irrelevant as the Material would Block the X-rays that formed inside🤷‍♂️ for breaking radiation you are looking at nucleus charge

[@kwokhardy2512]

If a proton can capture an electron to become a neutron, can a neutron capture a positron and become a proton? Assume the atom is fully ionized so the positron doesn't annihilate an electron.

[@SimonsNuclearchemistry]

(Where would the positron come from?) A neutron can become a proton, thats called a beta Minus decay ;D But there is a fun thing some scientiest have done. The fully ionized an electron capture nuclide so I could really decay since there where no electron and it then switched to beta Minus. And this electron from the beta Minus, could then be used to do electron capture. But that Story deserves its own Video :D
