In pair annihilation an electron and a position destroy each other to produce gamma radiations . How is the momentum conserved ?

Text Solution

Verified by Experts

in pair annihilation an electron and a positron destroy each other to produce `2gamma` photons which move in opposite directions to conserve linear momentum. The annihilation is shown below `._(0)e^(-1) +._(0)e^(+1) to 2gamma " ray photons "`
