0 1 A sigma-plus (Σ+
) particle and an unidentified particle Y are produced by the strong
interaction between a positive pion (π+) and a proton (p).
This interaction is represented by the equation:
π+ + p → Σ+ + Y

0 2 A box sample of bromine gas contains a mixture of two isotopes. An experiment is done
to find the percentage of each isotope in this sample.
0 2 . 1 In the experiment, the gas is ionised by a beam of electrons.
Explain how the beam of electrons causes a particle of the gas to have a charge
of +1e.
[2 marks]
The gas consists of bromine molecules. Each molecule has two bromine atoms.
The experiment finds that the bromine molecules contain 158, 160 or 162 nucleons.
Figure 1 shows the percentage of these different molecules in the sample
