What kind of photon is produced in annihilation? - ANSWER-gamma State what roles exchange particles can play in an interaction - ANSWER--Transfers energy -transfers momentum -Transfers force What is pair production? - ANSWER-Pair production is when one high energy photon spontaneously turns into a particle-antiparticle pair Give one difference and one similarity between a negative muon and an electron - ANSWER-Difference: The muon decays but the electron does not Similarity: Both are ne...

Isotope atoms which have the same number of protons and electrons but different numbers of neutrons. specific charge the ratio of charge to mass of a particle. Charge/Mass . Nuclear force an attractive force that acts between all nuclear particles that are extremely close together, such as protons and neutrons in a nucleus to hold the atom together. alpha particles (a) 2 protons and 2 neutrons (helium nucleus) beta particles (b) a high speed electron gamma...
