Find the energy released during the following fission reaction.
$^{235}_{\ 92}\text{U} + {^1_0\text{n}} \rightarrow {^{236}_{\ 92}\text{U}} \rightarrow {^{90}_{36}\text{Kr}} + {^{143}_{\ 56}\text{Ba}} + 3\ {^1_0\text{n}}$
| Mass (u) | |
|---|---|
| $^{235}\text{U}$ | $235\cdot 0439$ |
| $^{90}\text{Kr}$ | $89\cdot 9195$ |
| $^{143}\text{Ba}$ | $142\cdot 9206$ |
| $^{1}\text{n}$ | $1\cdot 0087$ |

During Rutherford’s gold foil experiment, it was observed that most of the $\alpha$-particles did not deflect. However, some showed a deflection of $180^\circ$.
What hypothesis was made to justify the deflection of $\alpha$-particle by $180^\circ$?
