[math] E_n = \frac{m}{2}\left( \frac{d}{t_n} \right)^2 [/math]
[math] \delta E_n = -\frac{2 \sqrt{2}}{\sqrt{m} d}\ E_n^{3/2} \delta t_n [/math]
- [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]
[math] d = 1.0\ m: \ \ \ \delta E_n = 0.42\ E_n^{3/2}\ MeV [/math]
[math] d = 1.5\ m: \ \ \ \delta E_n = 0.28\ E_n^{3/2}\ MeV [/math]
[math] d = 2.0\ m: \ \ \ \delta E_n = 0.21\ E_n^{3/2}\ MeV [/math]
