A Tritium gas target  bombarded with a beam of mono-energetic protons of K.E. 3 MeV. What is the K.E. of the neutrons which are emitted at an angle `30^(@)` with the incident beam? Atomic masses are: `H^(1)=1.007276`amu, `n^(1) = 1.008665`amu, `H _(1)^(3)= 3.06056` amu and `H_(e)^(3)=3.016030` amu.

Explanation

To solve the problem, we need to analyze the nuclear reaction that occurs when a Tritium gas target is bombarded with a beam of mono-energetic protons. The reaction can be represented as follows:

1. **Identify the Reaction**:
The reaction can be written as:
\[ ^1H + ^3H \rightarrow ^3He + n \]
where \( ^1H \) is a proton, \( ^3H \) is Tritium, \( ^3He \) is Helium-3, and \( n \) is a neutron.
