How far will the average neutral pion travel

Reference no: EM131002398

The main mode of decay for the neutral pion is into two γ-rays.

Part A. Write down the decay equation. Express your answer as a hafl-equation.

Part B. If the pion is moving (relative to the laboratory) at 0.81 c, and assuming the two γ-rays are emitted in the direction of the pion's velocity, how much energy does each have?

Part C. What are their wavelengths?

Part D. How far will the average neutral pion travel, in the laboratory frame, from its creation to its decay? The lifetime of the neutral pion is 8.4x10^-17s.
