Protons with kinetic energy T strike a stationary hydrogen target. Find the threshold values of T for the following reactions: (a) p+prarr p+p+p+ overset~p , (b) p+prarr p+p+pi^(0). |

Answer» SOLUTION :(a)For `p+prarrp+p+p+barp` `TgeT_(TH)=(16m_(p)^(2)-4m_(p )^(2))/(2m_(e ))C^(2)=6m_(p)c^(2)= 5.63 GeV` (b) For `p+prarrp+p+pi^(o)` `Tge T_(th)=((2m_(p)+m_(pi^(0))^(2))-4m_(p)^(2))/(2m_(p))c^(2)` `=((2m_(pi)+m_(pi^(o))^(2))/(2m_(p)))c^(2)= 0.280GeV` |
