Homework Statement
A meson with rest mass 135 MeV has kinetic energy 1 GeV. It decays into two photons. 1 photon moves in the direction of motion, 1 is in the opposite. What are the energies of the photons?
Homework Equations
[itex]E=m_0c^2[/itex]
[itex]E=hf[/itex]
[itex]λ'(\pi) = λ(\frac{(1+\beta)}{(1-\beta)})^{0.5}[/itex]
[itex]λ'(0) = λ(\frac{(1-\beta)}{(1+\beta)})^{0.5}[/itex]
The Attempt at a Solution
I obtained the speed of the meson from:
[itex]\gamma = (135 + 1000) / 135 = 8.407[/itex]
To give beta = 0.9929
Then I have used the beta formaulae to obtain:
[itex]λ'(\pi) = λ \times 16.755[/itex]
[itex]λ'(0) = λ \times 0.05968[/itex]
I think the ratio of these should somehow link to the ratio of the energies but I am not sure how!
Many Thanks
