Critical Angular Momentum

Formation cross-sections of evaporation residues have been measured in 19 F +159 Tb reaction at E lab =83, 88, 93, 98 and 103 MeV using recoil catcher technique followed by off-line gamma-ray spectrometry. Significant contribution from incomplete fusion has been observed at these low beam energies indicating the contribution to incomplete fusion from collision trajectories with angular momentum (l) less than the critical angular momentum for complete fusion (l cr (CF)) . Incomplete fusion cross-sections could be explained using a modified sum-rule model which allows effective competition from incomplete fusion for collision trajectories with l<l cr (CF) .

Right Ascension

A source of gamma rays has been found at right ascension 20h15m, declination +35°, with an uncertainty of 6° in each coordinate. Its flux is (1·5 ± 0·8) x 10-4photons cm-2sec-1at 100 MeV. Possible identifications are reviewed, but no conclusion is reached. The mechanism producing the radiation is also uncertain.

Low Altitude

AbstractThe experiment SONG (SOlar Neutron and Gamma rays) for the low altitude satellite CORONAS-I is described. The instrument is capable to provide gamma-ray line and continuum detection in the energy range 0.1 – 100 MeV as well as detection of neutrons with energies above 30 MeV. As a by-product, the electrons in the range 11 – 108 MeV will be measured too. The pulse shape discrimination technique (PSD) is used.
