A global study of the mass, energy, and angular distributions all products formed in collisions 180-MeV protons with $^{27}\mathrm{Al}$ is reported. These data are compared calculations based on intranuclear-cascade-plus-evaporation, preequilibrium hybrid, semiempirical models. It found that there evidence for enhanced energy deposition nucleon-nucleus relative to predictions intranuclear cascade calculations. In contrast, produce stronger damping, more consistent observed data.

A laser diode absorption spectrometer is coupled with a continuous dilution system for real-time monitoring of indigo dyeing denim yarn. The reduced form in the dyebath continuously pumped by peristaltic pump into mixing cuvette, where it diluted factor 80 aerated water and oxidized its stable form. This solution then sampling cell measurements. Monochromatic radiation emitted from at 635 nm used to measure shoulder broad peak. linear calibration curve obtained concentration range between 10...

Inclusive mass, energy, and angular distributions of all fragments with $A\ensuremath{\ge}6$ have been measured for alpha-particle-induced reactions on $^{12}\mathrm{C}$ at five energies between 49 159 MeV. From these data the evolution dominant reaction mechanisms energy is characterized. Based analysis mean value mass distribution, it appears that linear momentum transfer from projectile to target initially increases beam reaches a maximum about 30-40 MeV/nucleon. The low-energy are...

A post-irradiation radiochemical separation technique was tested for the determination of selenium levels in diet samples, collected by using a duplicate portion technique, from both rural and urban population groups Turkey. The involved sample irradiation, acid digestion, selective distillation, precipitation filtration steps. During separations it possible to determine yield each stable carrier. An average chemical 71 ± 3% obtained neutron activation analysis. For Samples regions,...

Projectilelike fragments were detected and characterized in terms of A, Z, energy for the reactions $^{37}\mathrm{Cl}$ on $^{40}\mathrm{Ca}$ $^{209}\mathrm{Bi}$ at E=7.3 MeV/nucleon, $^{35}\mathrm{Cl}$ E=15 angles close to grazing angle. Mass charge distributions generated N-Z plane as a function loss, parametrized their centroids, variances, coefficients correlation. The results are compared predictions two current models based stochastic nucleon exchange mechanism. drifts mass centroids...

Mass, energy, and angular distribution data for fragments with $A\ensuremath{\ge}6$ produced in intermediate-energy proton- alpha-particle-induced reactions on $^{12}\mathrm{C}$ $^{16}\mathrm{O}$ nuclei are compared the results of an intranuclear cascade calculation followed by deexcitation residual via a Fermi breakup mechanism. In this latter step all possible particle-stable exit-channel states included phase space available decay. The shapes distributions reproduced successfully...

Abstract The quality of sugar beet is affected by harmful nitrogen compounds. Although one the essential elements for plants, introduction excess as fertilizer to soil increases containing compounds in which deteriorates production. Hence, concentration soluble beets was monitored a routine process industry. In this work, low cost, but very long life time laser diode spectrometer, developed continuous monitoring amino beets.

A global study of the mass, energy and angular distributions all products formed in collisions 180‐MeV protons with 27Al is reported. These data are commpared semiempirical intranuclear‐cascade‐plus‐evaporation calculations, as well from recent fission‐fragment correlation studies intermediate‐energy light‐ions incident on heavy target nuclei. It found that there substantial evidence for enhanced deposition nucleon‐nucleus relative to predictions intranuclear cascade calculations.
