Prompt fission $\ensuremath{\gamma}$ rays (PFGs) resulting from the $^{240}\mathrm{Pu}(d,p\mathrm{f})$ reaction have been measured as a function of fissioning nucleus excitation energy ${E}_{\text{x}}$ at Oslo Cyclotron Laboratory. We study average total PFG multiplicity per fission, released and energy. No significant changes in these characteristics are observed over range $5.75<{E}_{\text...
The systematic evaluations of spectrum averaged cross sections dosimetric reactions over a broad range energies were performed in 252 Cf (spontaneous fission) and 235 U(n th ,f) neutron fields. sources used this study LR-0, VR-1 zero power research light water reactors, LVR-15 10 MW reactor, source with emission specified precisely by the manganese sulphate bath. All spectral inferred from meas...
A dedicated experimental program, devoted to reaching a full comprehension of the proton-induced spallation reactions, started in 1996 at the GSI. The accurate knowledge of these reactions is relevant both for the development of methods of incineration of radioactive waste [1] and for the production of secondary beams [2]. Within this program, the first ever complete survey on nuclide productio...
We investigate the asymptotic properties of two reaction–diffusion systems. The first is an annihilation/scattering system with the reactions 2A → ∅, 2A → 2B, 2B → 2A, and 2B → ∅. The second one consists of competing annihilation and fission processes, 2A → ∅ and 2A → (n+2)A. We find that both these diffusion–limited reaction systems belong to the same universality class as the single species a...
The heavy ion interaction of 11.67 MeV/u 197Au+ 197Au has been investigated using mica as a passive detector. By employing Solid State Nuclear Track Detection Technique the data of elastic scattering as well as inelastic reaction channel was collected. The off-line data analysis of multi-pronged events was performed by measuring the three-dimensional geometrical coordinates of correlated tracks...
conclusions our results demonstrated no significant correlation between the ird5 lifespan and the trehalose concentration. likewise, the correlation between lifespan extension, trehalose accumulation, and cellular resistance to hydrogen peroxide was not significant. results the lifespan of the ird5 mutant was significantly longer that of either the ird11 mutant or the wild type cells. under rep...
The thick target neutron energy spectra of the reaction Be(p,n) were measured 9 at several angles for proton bombarding energies of 3.0, 3.4, 3.7, 4.0 and 5.0 MeV. Time-of-flight techniques were used to determine the neutron energy spectra and to discriminate against background radiation. By using lithium-loaded glass scintillators and low proton pulse rate frequency, the neutron spectra have b...
