[math] E_n = \frac{m}{2}\left( \frac{d}{t_n} \right)^2 [/math]

[math] \delta E_n = -2\ E_n \frac{\delta t_n}{t_n} = -\frac{2 \sqrt{2}}{\sqrt{m} d}\ E_n^{3/2} \delta t_n [/math]


  • From NaI detector measurements [math]\delta t_n = 15\ ns[/math]
  • [math] mc^2 = 938\ MeV [/math]

[math] d = 0.5 m\: \ \ \ \delta E_n = 0.83\ E_n^{3/2}\ MeV [/math]
