Nuclear shapes from alpha-gamma-ray angular correlations.
The angular distribution of alpha particles with respect to the spin direction of the residual nuclei is used to probe the shapes of the emitting systems. Two compound systems have been studied: ' Yb and " Sn. Deformed emission shapes are required in order to understand the alpha-gamma correlations in the ' Yb system, but not for the " Sn compound system. These conclusions are identical to thos...
متن کاملAngular Correlations of the Mev Cosmic Gamma Ray Background
The measured cosmic gamma ray background (CGB) spectrum at MeV energies is in reasonable agreement with the predicted contribution from type Ia supernovae (SNIa). But the characteristic features in the SNIa gamma ray spectrum, weakened by integration over source redshifts, are hard to measure, and additionally the contributions from other sources in the MeV range are uncertain, so that the SNIa...
متن کاملStudy of carbonic anhydrase using perturbed angular correlations of gamma radiation.
The angular correlation of the 150-247 kev gamma-ray cascade of (111m)Cd is strongly perturbed when this nucleus is bound to the enzyme carbonic anhydrase. A comparison of the perturbed angular correlation for the apoenzyme with that for native carbonic anhydrase confirms that the (111m)Cd binds at the active region of the enzyme. These results provide good evidence that the perturbed angular c...
متن کاملGamma - Gamma , Gamma - Electron Colliders ∗
It is very likely that in 3-4 years the construction of one or two linear colliders with c.m.s energy up to 0.5–1.5 TeV will be started. Besides eecollisions, linear colliders give a unique possibility to study γγ and γe interactions at energies and luminosities comparable to those in ee collisions. High energy photons for γγ and γe collisions can be obtained using laser backscattering. These t...
متن کاملNo Evidence for Gamma-Ray Burst/Abell Cluster or Gamma- Ray Burst/Radio-Quiet Quasar Correlations
We examine the recent claims that cosmic gamma-ray bursts are associated with either radio-quiet quasars or Abell clusters. These associations were based on positional coincidences between cataloged quasars or Abell clusters, and selected events from the BATSE 3B catalog of gamma-ray bursts. We use a larger sample of gamma-ray bursts with more accurate positions, obtained by the 3rd Interplanet...
