The Scattering of α <strong>and</strong> β <strong>Particle</strong>s by Matter <strong>and</strong> theStructure of the AtomE. Rutherford, F.R.S.*Philosophical Magazine (1911)* Rutherford realized that such large deflection could notpossibly be resulted from a single scattering in theThomson’s model.* However, he was able to show that the probability of multiplescatterings was far too small to explain the observations.* Since electric field is proportional to 1/r 2 , such high fieldrequires concentration of charge to a very small r.* The positive charge CANNOT be the ‘bread’ surroundingthe electrons – all the charge must be concentrated to avery small NUCLEUS.
