 Ignore the above message left by Pratyya Ghosh, who was bit too enthusiastic in fighting vandalism. Just to let you know that the original content was correct, as the e Geiger–Marsden experiment was designed to probe the structure of the atom, rather than to prove it. The structure of the atom was unknown at the time, so any experiment investigating it at the time was more a "let's do it and see how things come out, then we'll try to make sense of the results". 

 PS: BTW, if you are interested in physics, considered joining WP:PHYS WikiProject Physics. It's a group of people interesting in improving physics-related content on Wikipedia.
