Semi retired old time computer nerd who started programming on a Commodore Pet.

Since I'm also active in the Physics forum I should add that I started as a theoretical chemist, moved into solid state photochemistry and finally worked in industry as a colloid scientist. I only became a full time computer nerd in 1997.

comment Neutron-Antineutron creation/annihilation data
Bearing in mind that the neutron is a composite of quarks and gluons the neutron-antineutron reaction is going to be exceedingly messy. The probability that it will produce just two photons is vanishingly small. I'm sure Anna posted experimental data on proton-antiproton products in an answer (and it was messy) but I can't find the question ...
