    Notes: Abstract An improved set-up is described which is universally applicable in electrooptic research work on liquid crystals. The main part of the test circuit consists of a highly stabilized and dc-free square wave generator with swept amplitude. An additional sine wave modulation with very good linearity up to high voltages allows capacity versus voltage measurements in a large frequency range. Measurements in the nematic phase of ap-disubstituted phenylcyclohexane (PCH) are reported as an example of the high performance of this set-up.

    Multiple electromagnetic excitation with relativistic heavy ions (1989)

    Notes: Abstract The multiple electromagnetic excitation with fast projectiles (heavy ions) is studied theoretically in the sudden approximation. Of special interest is the excitation of rotational states coupled to giant (dipole) vibrations. Closed form expressions are obtained for the excitation of a rigid rotor. The strong pulse of high energy equivalent photons in relativistic heavy ion collisions opens up new possibilities for nuclear structure studies, not possible e.g. with electron scattering or nuclear Raman scattering. It is also pointed out that the “Brink-hypothesis” can be investigated in a new way by means of multiple electromagnetic excitation with relativistic heavy ions of low lying states coupled to the giant dipole mode.
