Notizen: Abstract It has been observed that the separation between the absorption and the emission bands of a fluorescent dye is smaller in a rigid polymer matrix than in the liquid monomer. Low temperature measurements have been carried out in order to understand this phenomena. It has been found, that the molecular mobility of the matrix, in which the dye is dissolved, plays an important role. By doping the rigid matrix with molecules of high mobility, the separation between the absorption and emission bands can be increased. A nearly complete separation can be achieved by this doping method if the difference of the dipole moments in the ground and excited states of the dye molecules is very large. This allows, for example, to increase the brightness of the fluorescence-activated liquid-crystal display (FLAD) and the efficiency of solar collectors based on fluorescent dyes.

Notizen: Abstract The sequential break-up of 156 MeV6Li projectiles colliding with208Pb has been investigated in the very forward angular hemisphere in order to explore the role of the Coulomb and nuclear interaction in inducing projectile break-up processes. The experiments use the Karlsruhe spectrograph “Little John” with a newly developed technique to detect efficiently break-up pairs ofα-particles and deuterons emitted with small relative energies and within a small opening angle. The observed differential cross section for the projectile excitation6Li→6Li* (I=3i +) has been analysed (together with forward elastic scattering) by a coupled channel approach, and various sensitivities to the nuclear potential and other ingredients have been studied. We conclude, that in the angular region below half the grazing angle the excitation is completely due to the Coulomb force. This feature is a basis for an application of the disintegration approach for studies of radiative capture cross section of astrophysical interest.

Notizen: Abstract The high flux of equivalent photons present in relativistic heavy ion collisions of two chargesZ 1 andZ 2 gives rise to the collision of two equivalent photons. The cross-sections for various processes are directly related to the correspondingγ- γ cross-sections. As compared toγ- γ physics being studied at e+ e− colliders, we find that high energy states will not be so easily accessible at the existing facilities, however, the enhancement factor (Z 1 Z 2)2 in the expression for the cross section will provide very large photon fluxes for lower energies.
