2026-Mar-06 16:54:42 To approximate the expected number of multi-way collisions, I used a simple physical model where nuclei are spheres with density 2.5e17 kg/m^3 and they interact if the centre of one goes within another. Then in the code below I work out a "volume fraction" of the focal ellipsoid that is filled and an "area fraction" that is filled in 2D projection seen from the side with largest area. 2-way collisions are expected to occur N*Afrac times and this matches the traditional luminosity formula if you expand it out. True 3-way collisions require an additional factor of Vfrac to get the 3rd nucleus exactly where you want it at that instant, whereas chained 3-way collisons (two consecutive collisions within the focal point) require only a factor of Afrac, which is larger. This gave the graphs in my previous post. The numbers behave similarly with a small shift for different nuclei although I used calcium as a mid-Z choice. Things like the D-T resonance are not included!

2026-Mar-03 22:53:57 You might wonder why I put hashtags on my posts now. It started when Elon Musk said he didn't like hashtags because AI could do the same job. That made me realise that hashtags are valuable human-classified data, so I should use them more.
Also they work quite well as a topic search on Mastodon. |
2026-Mar-03 22:05:43 I noticed before that you can approach the nuclear density by taking an ultra-cold Coulomb crystal, putting it through a TeV-scale particle accelerator and then focussing it to an extremely small spot. But does anything interesting happen with a slightly smaller accelerator? It turns out that pair-wise nuclear interactions within the imploding beam are joined by 3-way and 4-way ones as energy and density increase. Depending on how stable the intermediate products are, you can also get chained collisions within the bunch diameter. #physics #accelerators
3-way collisions are usually only seen inside the cores of stars and, if there are super-heavy elements yet to be found, this may be a way of making them.
