His lectures were accessible, his manner of speaking clear, convincing, and often amusing. The Rutherford model of the atom, put forward in 1911, proposed a nucleus, where the majority of the particle's mass was concentrated, according to Britannica. In 1903 he was able to deflect it in electric and magnetic fields, thereby showing its positive charge, but his charge-to-mass ratio measurement lacked the precision required to distinguish between a helium atom with two charges and a hydrogen atom with one charge. He helped create the Geiger-Nuttall rule. Physicists got their first look at the structure of the atomic nucleus. Yet, when Geiger and Marsden conducted their eponymous experiment, they found that in about 2% of cases, the -particle underwent large deflections. Tweet This, DEA can seize your money without a court decision, without even raising charges. Their results were published in German in Vienna in 1912 and in English in the Philosophical Magazine in April of 1913.
