## Homework Statement

Explain why the scattering of [itex]\alpha[/itex] particles at very small angles disagree with the Rutherford formula.

## Homework Equations

N/A

## The Attempt at a Solution

I find resources from webs and get some information about the failure of Rutherford's formula. It occurs only at the distance of closest approach being less than the diameter of the nucleus and this can happen if (a) the angle of scatter is large or (b) the energy of the particle is large enough, which is on the contrary of the problem statement.

I am thinking the problem statement is wrong.

Could anyone help me?

Regards.
