Abstract Nuclear reactions have been the major source of knowledge in the field of nuclear physics in general. A nuclear reaction is an interaction between two or more nuclei, forming a system, which is brought to a different state than the initial one. Geiger and Marsden performed the first nuclear reaction experiment in 1909 without them being actually aware of it, when they studied the scattering of alpha particles from a gold target. A broad set of theories have been developed in order to explain the different measurements. The pioneer in this sense was Ernst Rutherford when he inferred in 1911 that an atomic model with a small compact positively charged nucleus was more suitable for explaining the angular distribution obtained in the Geiger and Marsden experiment, instead of the previous description of the atom by J.J. Thomson. Nowadays, there are many theories available that describe different features of the nuclei. Unfortunately, the more accurate they are, the more complicated they usually become, so it is the task of the physicist to select the most suitable model depending of the needs in each case. |
