Theory of Dopler Broadening

Photon emmision along direction of fission fragment velocit

[math]E_{shift} = E_{photon} \frac{1-\beta \cos(\theta_{photon})}{\sqrt{1-\beta_i^2}}[/math]

[math]cos\theta_{photon1}[/math]

Photon emission off fission fragment velocity axis

Cf-252 Fission

Photon Spectra from Cf-252
