  • We report the method and results of measurements of angular distributions of fragments in the (..gamma..,f) reaction for /sup 232/Th, /sup 236/U, and /sup 238/U carried out in connection with the investigation of the properties of deep sub-barrier photofission: the isomeric shelf phenomenon, disappearance of the angular anisotropy (/sup 236,238/U), and the absence of this effect and of the sub-barrier enhancement of quadrupole photofission in /sup 232/Th. The experimental data presented permit an understanding of the nature and relation of these properties in terms of the concept of a two-humped fission-barrier structure.
  • The 21-cm deep-sky radio-source distribution data acquired by Windhorst (1984) with the Westerbork synthesis radio telescope were analyzed. In some of the survey fields, significant departures from a Poisson distribution were found. The correlation analysis of the data provides evidence for an anisotropic radio source distribution and supports the existence of a distant (redshift z of about 0.54) supercluster of galaxies. 5 references.
  • An 8-mm radiometer system with a degenerate parametric amplifier was launched on the high-apogee (7 x 10/sup 5/ km) Prognoz 9 satellite in July 1983 to map the large-scale anisotropy of the cosmic background radiation. Early results indicate that the amplitude of the dipole and any quadrupole component is measurable to 0.1-mK rms accuracy, and by the end of the experiment the error should be lower. With 95% confidence the strip of sky investigated thus far exhibits no quadrupole component above the 0.2-mK level.
