B-particles inappropriate for scattering experiment

Click For Summary
SUMMARY

The discussion centers on the inappropriateness of β-particles for α-particle scattering experiments, which are pivotal in demonstrating the existence and size of atomic nuclei. Key reasons include the variable energy levels of β-particles, which complicate the scattering angle distribution, and their small mass, which leads to significant deflection by orbital electrons. These factors hinder the ability to draw definitive conclusions from the scattering results, unlike α-particles that provide clearer insights into nuclear structure.

Homework Statement


The results of the α-particle scattering experiment provided evidence for the existence and small size of the nucleus.
The α-particles in this experiment originated from the decay of a radioactive nuclide. Suggest two reasons why β-particles from a radioactive source would be inappropriate for this type of scattering experiment.

2. The attempt at a solution
I thought because they are negatively charged and so they will get attracted to the positive nucleus, and also because they are too small, but they are not acceptable. The answer is that they have a range of energies / they are deviated by orbital electrons/ has small mass .

What effect does having a range of energies have? And also small mass? Why.. And why can't I say they are attracted to the nucleus?

The distribution of scattering angles depends on the energy. If you have a large distribution for this energy, it gets harder to draw conclusions.

The deflection by orbital electrons, as mentioned.

You can say that, and it is true, but it would not change the result of the experiment significantly.
