So say if a charged particle decays and one of the products is neutral, which then goes on to decay into two oppositely charged particles, then the distance where the track disappears - I.e where the neutral particle was - is caused by the time it takes for that particle to be destroyed? Sorry...
I'm studying A Level physics. I've read that a bubble chamber only shows up particles with a charge, as they ionize the hydrogen in the chamber, leaving tracks, whereas neutral particles don't show up. Is it therefore true then that only charged particles ionize? Because UV-radiation is ionizing...
