Fission Reaction Event Yield Algorithm FREYA 2.0.2

Fission Reaction Event Yield Algorithm FREYA User Manual

From nuclear materials accountability to detection of special nuclear material, SNM, the need for better modeling of fission has grown over the past decades. Current radiation transport codes compute average quantities with great accuracy and performance, but performance and averaging come at the price of limited interaction-by-interaction modeling. For fission applications, these codes often l...

Applications of Event-by-Event Fission Modeling with FREYA

The recently developed code FREYA (Fission Reaction Event Yield Algorithm) generates large samples of complete fission events, consisting of two receding product nuclei as well as a number of neutrons and photons, all with complete kinematic information. Thus it is possible to calculate arbitrary correlation observables whose behavior may provide unique insight into the fission process. We firs...

Fission-residues Produced in the Spallation Reaction

Fission fragments from 1 A GeV U projectiles irradiating a hydrogen target were investigated by using the fragment separator FRS for magnetic selection of reaction products including ray-tracing and E-ToF techniques. The momentum spectra of identi ed fragments were analysed to provide isotopic production cross sections, ssion-fragment velocities and recoil momenta of the ssioning parent nuclei....

The paper discusses general problems in using PEG for conjugation to high or low molecular weight molecules. Poly (ethylene glycol) (PEG) is a highly investigated polymer for the covalent modification of biological macromolecules and surfaces for many pharmaceutical and biotechnical applications. PEGylation is the process of covalent attachment of polyethylene glycol (PEG) polymer chains to ano...
