As we know in Rutherfords gold foil experiment, Rutherford shot decayed alpha particles into a very thin sheet of gold foil, and after many trials looking into a telescope they observed that about 1 in 20000 alpha particles bounced off this "concentrated, positively charged nucleus' more than 90 degrees. Since they were using the naked eye and with a microscope counting the light beams from the ZnS screen, is this a pure estimate or is there an actual mathematical formula to deduce this number?
