Suppose you were to try to create a
proton-antiproton pair by annihilation of
two very high-energy gamma rays of the
same wavelength heading toward each
other. The proton and the anti-proton
have the same masses, but opposite
charges. What would be the minimum
energy needed for each photon? (e = 1.60
× 10-19 C, m proton = 1.67 × 10-27 kg, c =
3.00 × 108 m/s)
939 MeV
O1.022 MeV
O 12.2 MeV
O 1880 MeV
What is the minimum proton energy required to produce an antiproton in a collision with a stationary proton?
A proton‑antiproton annihilation takes place, leaving two photons with a combined energy of 2.50 GeV.
Find the kinetic energy Kp of the proton if the proton had the same kinetic energy as the antiproton.
Find the kinetic energy Kp′ of the proton if the proton had 1.25 times as much kinetic energy as the antiproton.
