Strutinsky-type calculations indicate that the potential energy favors four channels in the nuclear fission of 252Cf. The connection of this finding with experimental results on the dis­ tribution of fragment mass, total kinetic energy, neutron multiplicities, and relative abundances is discussed. Similar calculations for 227Ac, 236U, and 258Fm show that the changing preponder­ ance of the four...

2014 It has been shown recently that fast heavy ions can induce a mild desorption of organic molecules deposited on a thin foil, when passing through the foil. A time of flight mass spectrometer, originally developed to identify the mass of radioactive nuclei, has been slightly transformed to allow the determination of the mass of large molecules. The desorption of the molecules is at the prese...

BACKGROUND In neutron interaction with matter and reduction of neutron energy due to multiple scatterings to the thermal energy range, increasing the probability of thermal neutron capture by neutron captures makes dose enhancement in the tumors loaded with these materials. OBJECTIVE The purpose of this study is to evaluate dose distribution in the presence of 10B, 157Gd and 33S neutron captu...

Here we present the ELI Gamma Above Neutron Threshold setup recently implemented at Extreme Light Infrastructure – Nuclear Physics. The main goals of detector array are presented, as well mechanical design and performance individual detectors. In addition, have performed Geant4 simulations for realistic beam conditions. Finally, show a whole outline analysis procedure complex experimental measu...

of the triple fission of 252Cf . Further on, investigations on hypernuclei and the possible production of antimatter-clusters in heavy ion collisions are reported. Various versions of the meson field theory serve as effective field theories as the basis of modern nuclear structure and suggest structure in the vacuum which might be important for the production of hyperand antimatter. A perspecti...

The quenching factor of the proton recoil in the stilbene scintillator was measured with a 252Cf neutron source and was found to be 0.1 – 0.17 in the recoil energy range between 300 keV and 3 MeV. It was found to depend on the direction of the recoil proton. The directional anisotropy of the quenching factor could be used to detect the wind of the WIMPs caused by the motion of the earth around ...

A direct comparlson Is made of the mass spectra of several involatile compounds obtained by using 252Cf ission fragment lonlratlon and iow-energy Ion bombardment using klloelectronvol! K+ and Cs’ ions. The comparisons were made on the same samples mounted on the same folk and mass determinations were made by using the time-of-flight principle. A very hlgh degree of slmllarity was observed In th...
