4.3. Partial Cross Sections - 16 - S. Cierjacks, P. Forti, D.Kopsch, L. Kropp Measurements with the fast coincidence apparatus (liquid scintil lators) have been completed / 1 / . The solid state scattering chamber has been equiped with additional semiconductor telescopes. A, more sophisticated programm was written which allows the particle assignment and automatic corrections of char ged particle time-of-flights during the measurement. By applica tions of commercial zero-cross-over circuits (EGG 100 M module a further improvement of the time resolution was obtained. A new approach to measure inelastic neutron scattering would be to use the Karlsruhe cyclotron as the neutron source. Since this source delivers a continuous neutron spectrum the incoming neutron energy as well as the>energy of the scattered neutrons must be deduced from the experiment. Conclusive results can be obtained either by a double time-of-flight experiment or by a single time-of- flight experiment using Ge(Li) solid state detectors. In the latter case the total time-of-flight should be measured simul taneously with the V-energy. Evaluating both the pulse height and the time-of-flight information allows to determine the inital energy as welD l as the energy of the scattered meutrons. The construction of suitable detectors is under way. An on-line program which will be written, which can be used to store the data as a function of the incident neutron time-of-flight» scattering angle and time-of- flight after scattering or the pulse height of the Ge(Li) detectors respectively.
