Energy Distribution of Protons from a Target Bombarded by 190 MeV Deuterons


Book Description

Previous experimental work by Helmholz, McMillan, and Sewell has shown that a narrow beam of high energy neutrons is produced when a beam of 190 Mev deuterons strikes a thin target. The mechanism for the production of the eutrons has been discussed by Serber, who describes a process in which the proton in the deuteron strikes the edge of nucleus in the target and is stripped off, while the neutron misses and continues on its way. It is to be expected that an equal umber of high energy protons are produced by stripping processes in which it is the neutron that hits the nucleus. These high energy protons have been detected by (1) carbon activation, and (2) photographic plates. Both methods give energy distributions in agreement with the energy distribution predicted for protons produced by the stripping process.




Neutron Production by Protons (190 to 268 MeV) in a Water-cooled Tantalum Target


Book Description

Calculated results are presented for the number of neutrons produced, the neutron production spectra, and energy deposition as a function of depth in the target when protons in the energy range 190 to 268 MeV are incident on a water-cooled tantalum target.










Elastic Scattering of High Energy Electrons from Deuterium


Book Description

The purposes of the present work are: (1) To investigate the method of elastic electron-deuteron scattering by detection of the recoil target nucleus. (2) To evaluate existing theory for the scattering process in light of the recent advances in understanding nucleon structure and the nuclear force. (3) To provide experimental data at values of the momentum transfer where none had previously existed. Some fundamental preliminary considerations are discussed in Chapter II. Chapter III contains a summary of theoretical aspects of the problem and results of calculation. Some basic experimental questions are answered in Chapter IV. In Chapter V the experimental apparatus is described. The data, method of analysis, and corrections are discussed in Chapter VI. In the last chapter a comparison of the experimental results with theoretical predictions is made, and conclusions and suggestions for further work are given.
