# Rutherford's Gold Foil Experiment

Can anybody explain how Rutherford bombarded a 0.0004 cm thick gold foil? How did he put it in a photographic sheet? Wasn't the foil too thin to be held? How did he know that the atoms were deflected at various angles? Did he calculate every alpha particle's angle of deflection?

edit: There is a very good book, The fly in the Cathedral which describes this period, the science and the experimental techniques. High vacuum stuff is a pain the ___ even with modern quick connects and Helium leak detectors, doing it with string and sealing wax (literally) was quite a challenge.
