The formation of the natural isotope of Be9 and the possibility of preparing it in a nuclear laboratory

Nucleosynthesis if fairly well understood to generate very little Be. Maybe your guy was talking about nuclear spallation, which is not fission per say and happens in interstellar medium. Not in star core. Due to its short half life, Be7 can be picked up from furnace filters, as it is continuously generated (much like C14) It is sometimes used as a metric for sediment deposition and in short to medium term forensic analysis when a body is found in open air. I demonstrated that fact in a video a few years ago. As to the second part of your question, I second J_sum1 ... "Just what kind of lab do you think you need to create and isolate isotopes?" and why on earth would you want to generate stable wildly available cheap stable isotope ?

Thank you and j sum1, you're a real expert! Yes, I'm sure the man meant the nuclear spallation. I guess he meant the outer layers of some stars, or interstellar space. His name is Josip Kleczek, and there's a planetoid named after him, I think.
I meant creating beryllium from other elements, not isolating its stable isotope. I've been collecting the minerals of beryllium since childhood and admiring its gems, and when I was a teenager, I dreamed of creating stable beryllium in the lab so I could synthesize this gems. Back then, beryllium was completely inaccessible to the common "mortal"- human in our country. Today, the idea of his synthesis appeals to me out of curiosity and out of interest. I know it would be very expensive and there would be problems and I would only get a tiny amount, but it would be a childhood dream come true for me

I'm not quite sure how the nuclear part fits in with gem chemistry, but I can find no nuclear reaction for you to create beryllium. The smallest cluster decay is C12, and I believe even hydrogen bombs do not create Be. I wonder how much energy would be needed for spallation? Maybe Fermilab could do it?

3He and 4He can fuse to produce Be7 and a gamma, when using the word "synthetize" in organic chemistry, it means something different when talking about elements and isotopes. Hence the misunderstanding... This IS a scientific oriented site .

I'm sorry for not using the right term, English is not my native language and I didn't speak English often...I'll try to do better... What was the correct term in English I should have used for this in the language of nuclear physicists? Thank you for giving me that reaction, but I'm interested in Be9 especially...Is there an equation, please, that describes the formation of Be9 in nature and then the one that works in the nuclear physics lab as well? I don't mean nuclear spallation! That's certainly unrealistic in a nuclear lab)!

Thank you, I meant that if there was a possibility in the nuclear physics lab to create Be9 in significant quantities, then the nuclear part of the job would be done. The other, chemical part of the job would be to convert Be into BeO. BeO is a precursor to the synthesis of all kinds of gems, that contain beryllium.
Of course, I didn't mean nuclear spallation by nuclear laboratory preparation! It was clear to me that this was a task beyond manpower. But, as you mentioned, you haven't found any reaction that describes the formation of Be9, so it's a huge challenge to find that reaction! Maybe our member Neptunium will come up with something! What about FermiLab, will it accept the challenge ?

This conversation seems reminiscent of something… Let me say that the physical properties of beryls, the chemical properties of beryllium and the nuclear properties of Be isotopes are three extremely different fields which you seem to have conflated. In this third field, nuclear properties, there is almost nothing that is accessible to an amateur. With the right (expensive) gear you can do a bit of detection. But no synthesis. No isolation. And, no, Fermilab will not be interested and nor will anyone else. Time to do some reading rather than posting some half-baked nonsense.
