Consistent calculation and analysis of neutron scattering data of Th with optical model, semiclassical model includes both the Hauser-Feshbach theory and the exciton model, and the coupled channel theory is carried out in the En≤20 MeV energy range based on the experimental data of total, nonelastic-scattering, fission, and other reaction cross section and elastic-scattering angular distributio...

Ruthenium-103 is the parent isotope of 103mRh (t1/2 56.1 min), an isotope of interest for Auger electron therapy. During the proton irradiation of thorium targets, large amounts of 103Ru are generated through proton induced fission. The development of a two part chemical separation process to isolate 103Ru in high yield and purity from a proton irradiated thorium matrix on an analytical scale i...

Protein kinase D (PKD) binds to a pool of diacylglycerol (DAG) in the TGN and undergoes a process of activation that involves heterotrimeric GTP-binding protein subunits betagamma to regulate membrane fission. This fission reaction is used to generate transport carriers at the TGN that are en route to the cell surface. We now report that PKD is activated specifically by G protein subunit beta1g...

The yields and velocity distributions of heavy residues and fission fragments from the reaction of 20 MeV/nucleon 197Au + 90Zr have been measured using the MSU A1200 fragment separator. A bimodal distribution of residues is observed, with one group, resulting from peripheral collisions, having fragment mass numbers A= 160–200 while the other group, resulting from “hard” collisions, has A = 120–...

A high-resolution study of fragment-fragment-γ triple coincident measurements of the symmetric-mass fission exit-channel from the Si+Si reaction has been performed at the VIVITRON Tandem facility by using the EUROGAM Phase II γ-ray spectrometer. The bombarding energy Elab( Si) = 111.6 MeV has been chosen to populate a well known quasi-molecular resonance in Ni. Evidence is presented for a selec...

We propose an experiment to isotopically identify and determine the production cross sections of residual nuclei in the fragmentation of very neutron-rich nuclei around Sn produced in the fission of relativistic U primary projectiles. These measurements will provide valuable information about a possible two-step reaction scheme (fission-fragmentation) to optimise the production of extremely neu...

This paper describes the effect of input uncertainties on a set integral parameters (kinf, nuclide compositions) associated with validation CASMO-5 against PIE data. The nuclear data under consideration are cross-sections, fission spectrum and neutron multiplicities yields. Various sources covariance information considered, novel ones (ENDFB-VIII.0, JEFF-3.3) as well more widely distributed (JE...

Complex structural effects in the nuclide production from the projectile fragmentation of 1 A GeV U nuclei in a titanium target are reported. The structure seems to be insensitive to the excitation energy induced in the reaction. This is in contrast to the prominent structural features found in nuclear fission and in transfer reactions, which gradually disappear with increasing excitation energ...

The production of heavy nuclides from the spallation-evaporation reaction of U induced by 1 GeV protons was studied in inverse kinematics. The evaporation residues from tungsten to uranium were identified in-flight in mass and atomic number. Their production cross-sections and their momentum distributions were determined. The data are compared with empirical systematics. A comparison with previ...
