    Notes: Abstract The data of fission fragment anisotropies measured for the system16O +209Bi in the centre of mass energy region of 73 to 95 MeV have been compared with the saddle point statistical model calculations. The corrections to the nuclear temperature and the spin distribution arising due to pre-fission neutron emission have been made. While the resultant calculations reproduce very well the data in the near- and sub-barrier energy regions, they deviate from the data at higher energies. This observation is similar to what was already reported for16O +208Pb system.

    Description / Table of Contents: Aus dem Polymer CR-39(DOP) wurden Thermoelektrete formiert, und die thermisch stimulierten Entladungsströme wurden gemessen. Die Einflüsse unterschiedlicher Formierungstemperaturen, unterschiedlicher Feldstärken und der Lagerzeit wurden untersucht, um das Elektretverhalten dieses Materials zu beschreiben. Die Polarisation ist dipolaren Ursprungs. Die Aktivierungsenergic und die Relaxationszeit wurden berechnet.
    Notes: Thermoelectrets of CR-39(DOP) were formed and their thermally stimulated discharge current studied. In the present work, effects of different forming temperatures, polarizing fields and storage times have been studies with a view to understand the electret behaviour of this material. The polarization seems to have a dipolar origin. The activation energy and relaxation times have also been calculated.
