Anisotropic n's vs. isotropic ones: Difference between revisions

Revision as of 15:01, 24 June 2011

"The observation were consistent with the assumption that anisotropic fission is due solely to photons with-in about 3 MeV of the fission threshold".

Winhold and Halpern, Phys.Rev. 103 4, 990 (1956)

Say we have only anisotropic neutrons

[math]\displaystyle{ \Theta = 0^o:\ 100\ n's }[/math]

[math]\displaystyle{ \Theta = 90^o:\ 125\ n's }[/math]

So the calculated asymmetry would be:

[math]\displaystyle{ A = \frac{125}{100} = 1.25 }[/math]
