"Q value" is defined as the clifference in kinetic between the final' particles and the tnitial particles. The "threshold energy energy is the minimum kinetic energy of the reaction prodlucts below which the reaction will not take place. la) calculate Q value of the reaction: P+ He - +He b) Determine the threshotd energy when the protons are Tncident on *He at rest. c) Determine the threshold on profons at rest. energy when the 4te are incidlent
