Oe possible decay mode of the neutral kaon is k0 s 1r0 , Ask an Expert

Academics

One possible decay mode of the neutral kaon is K0 S 1r0 + 1r0. The rest energies of the K0 and 1r0 are 498 MeV and 135 MeV, respectively. The kaon is initially at rest when it decays.

(a) How much energy is released in the decay?

(b) What are the momentum and relative directions of the two neutral pions (1r0)?
