Two spectroscopic techniques of the Rayleigh scattered light have been investigated. One investigation is on a method to measure the Rayleigh linewidth precisely. From the measurements it is found that the linewidth of the scattered light by the polystyrene latex particles in the buffer solution is significantly different from that obtained from the Einstein-Stokes relation. The other investigation is on an application of the spectroscopic method for the detection of the electrophoretic analysis. From the investigation it is found that the Rayleigh scattered spectral line shows the Doppler shift by the electrophoretic movement of the particle and that the electrophoretic velocity can be measured in real time.

In this paper a non-static solution for an elastic fluid distribution has been obtained which is conformal to flat space-time.

Glaser magnets are used in low energy beam lines for focusing ion beams and electrons. These are basically solenoid magnets with the difference that iron poles are inserted inside to enhance the field and thus the focal power. The field in a Glaser magnet is nearly Lorentzian. The transfer matrix, necessary for calculating the beam envelope through the magnet, is available for solenoids. But this is not available in the literature for Glaser magnets. We have calculated the transfer matrix for a Glaser magnet.

Counting losses of multichannelized delay lines are calculated and a delayed coincidence spectrometer is designed. As the results of the calculation, 10 delay lines are prepared as a multichannelized delay line in the spectrometer. In order to set the delay times of 10 delay lines exactly the same, a digitally controlled system is employed. The experimental results of counting losses and delayed coincidence rates show good agreements with the calculated results. According to the investigation of the counting loss of the multichannelized spectrometer, it is noted that the counting efficiency of the 10 channelized spectrometer is about 400 times better than that of a single channel spectrometer.
