Put the events that lead to Wu’s confirmation of Fermi’s theory of beta decay in the order they happened.
Other scientists tried the experiment with thin and uniform source material and confirmed Fermi had been correct all along.
Wu made a thin and uniform source using a radioactive solution with a special copper tool and placing a drop of radioactive solution on a film.
Wu decided not to use the same type of spectrometer the other physicists had used in their beta decay experiments.
Wu adapted the spectrometer so it could accommodate thinner sources of radioactive materials.
