Measurements of reaction cross sections are routinely used to deduce effective nuclear root mean square ~rms! radii by comparison with theoretical model predictions. Cross sections calculated using the optical limit Glauber model depend strongly on the rms radius of the density assumed for the projectile nucleus. We investigate such calculations by assuming a range of projectile density distrib...
Background and Purpose Activation of the defence reaction inhibits baroreflex response via intermediate rostro-ventromedial medulla (B3 raphé) nucleus tractus solitarius (NTS). Our aim was to determine whether how inhibition, induced by disinhibition rostral cuneiform (part pathway), involves 5-HT neurons in B3 5-HT3 receptors NTS. Experimental Approach We performed immunohistochemistry anatomi...
Limits on the low energy antinucleon-nucleus annihilations from the Heisenberg principle. Abstract We show that the quantum uncertainty principle puts some limits on the effectiveness of the antinucleon-nucleus annihilation at very low energies. This is caused by the fact that the realization a very effective short-distance reaction process implies information on the relative distance of the re...
We perform a detailed analysis for the structure of $$^{31}$$ F, which is candidate halo nucleus. calculate radius and total reaction cross section using three-body wave function $$^{29}$$ F+n+n discuss how competition between neutron-pairing single-particle energy induces structural changes F. The present further clarifies new aspect anti-halo effect that suppresses in ground state.
Nucleon total reaction and neutron total cross sections to 300 MeV for 12C and 208Pb, and for 65 MeV scattering spanning the mass range, are predicted using coordinate space optical potentials formed by full folding of effective nucleon-nucleon interactions with realistic nuclear ground state densities. Good to excellent agreement is found with existing data.
we describe here a suitable approach for the synthesis of n-unsubstituted monocyclic b-lactams under mild reaction conditions by the annelation of imines with substituted acetylchlorides. in this method the reaily available phtalimidoacetyl chloride were allowed to react with - dibenzylideneiminotoluene (hydrobenzamide) in the presence of an equimolar amount of triethylamine in refluxing toluen...
Based on the spectator expansion of multiple scattering series we employ a chiral next-to-next-to-leading order (NNLO) nucleon-nucleon interaction same footing in structure as well reaction calculation to obtain an leading-order consistent effective potential for nucleon-nucleus elastic scattering, which includes spin struck target nucleon. As example present proton off $^{12}$C.
Transverse momentum spectra of the non-strange, strange and multi-strange particles in central peripheral Copper-Copper, Gold-Gold Lead-Lead collisions are analyzed by blast wave model with Boltzmann Gibbs statistics. The results approximately agreement experimental data measured BRAHMS, STAR, SPS, NA 49 WA 97 Collaborations special transverse ranges. Bulk properties terms kinetic freeze out te...
Methanolysis of intervertebral disc samples at 600 was largely hydrolysis as shown by the absence of methylated derivatives on chromatograms of the reaction products. Extent of the reaction increased with acid strength; the products were the same. Maximum solubilization was about 80% and 50% for hyaline cartilage plate and nucleus pulposus samples, respectively. The results of aqueous acid (hyd...
