So, to create just one Au 79/197 atom, you need just under 40 collisions of He2/4 plus 37 extra neutrons at 0/1 atomic weight. (There are other ways, such as one simultaneous collision of between a Y39/89 + Zr40/91 + 17 neutrons ... but then still have to create the Yttrium39 and Zirconium40 (and find the 17 neutrons) in some earlier series of supernovas.) Once created, that single, little atom of
