Hence the energy of neutron is Σn = 6.6 mev
Explanation:
- 139 + 938 --> 939 + hv + e
- mn vn = Σ r / c
- Σn / Σ r = 1/2 mn vn^2 / c mn.vn = 1 / 2 Vc / c
- Σn / Σ r = 1/2 Σ r / mnc^2 = Σ / 1878
- Σn / Σ r + Σn = Σ r / 1878 + Σ r
- Σn / 138 = 138 - Σn / 1878 - 138 - Σn
- Σn = 138 - Σn / 2016 - Σn
- Σ n = 9 m eV
- mn . Vn = mn vn / √ (1 - β^2) = Σn / c
- Σn = 6.6 mev
Hence the energy of neutron is Σn = 6.6 mev
