Sweden and the European miracles : conquest, growth and voice : a survey of problems and theories /

This thesis deals with the measurement of the differential elastic scattering cross sections of the elements lead, mercury, tungsten, antimony, selenium and zinc for 14-MeV neutrons in the angular range from about 15˚ to 90˚. In the introduction in chapter 1 it is pointed out that a knowledge of these cross sections is important in connection with the so-called cloudy crystal ball model. In particular the scattering data for neutrons of intermediate energy (order of magnitude of 10 MeV) are a direct and sensitive test for the optical model, since the theory is directly applicable to the elastic scattering of neutrons of not too low energy. ....
