WebNegative pi mesons, or pions, are negatively charged particles that have a mass 273 times that of an electron. These are produced in a cyclotron or linear accelerator using 400 to 800 MeV protons that bombard a beryllium target. Pions exhibit a Bragg peak produced by elicited protons, neutrons, and α particles. Webv = 0.990 c; m = 9.11 × 10 −31 kg. List the unknown: K rel. Express the answer as an equation: K class = 1 2 m u 2. Do the calculation: K class = 1 2 m u 2 = 1 2 ( 9.11 × 10 −31 kg) ( 0.990) 2 ( 3.00 × 10 8 m/s) 2 = 4.0179 × 10 −14 J. Convert units: K class = 4.0179 × 10 −14 J ( 1 MeV 1.60 × 10 −13 J) = 0.251 Mev. Significance
