The Nuclear Fission Experiment


  1. Introduction.

  2. Topics of the experiment are:

  3. The Silicon Detectors picture.


Among nuclear reactions, fission is very spectacular and of the greatest practical importance. The most famous is that of 235U which, when bombarded by neutrons, splits into two fragments, which fly apart. This phenomenon is called fission (Hahn and Strassmann, 1939). It is accompanied by emission ("evaporation") of neutrons which can induce fission of another nucleus and thus offer the possibility of a chain reaction. Some heavy radioactive nuclei undergo fission spontaneously, without outside stimulation (spontaneous fission; Flerov and Peterjak, 1940). This mode of fission is being used in this experiment.

Topics of the experiment are:

-Understanding the physics of spontaneous nuclear fission.
-Experience in working with semiconducting silicon detectors and nuclear electronics.
-Experience with modern techniques of data taking procedure.
