We study the mechanisms of the homogeneous crystal nucleation from the supercooled liquid to the crystal phase in the Gaussian core model for colloidal suspensions with the aim to find optimal reaction coordinates. We introduce a set of novel collective variables based on the local structure of particles. By applying likelihood maximization of the committor function for the reweighted path ense...

Cross sections for the π+π− events arising due to the decay of ρ0 meson have been calculated. This rho meson is considered to produce coherently in the (p, p′) reaction on a nucleus. The distorted wave functions for the continuum particles and the rho meson propagator are described by the eikonal form. The sensitivity of the cross section on the pion emission angle as well as on the beam energy...

Spectroscopic investigation, on exotic nuclei, performed in two different experiments with secondary radioactive boron beams are discussed. Spectroscopic factors for the B+n bound-states are obtained by measuring momentum distribution of the B residual nucleus from knockout reaction of the B beam at intermediate energy. The momentum distributions are measured in coincidence with the emited γ-ra...

high spin states in the neutron rich nucleus 191os has been populated for the first time using the82se+192os deep-inelastic reaction at 460 mev beam energy using the alpi accelerators at the laboratorynazionali di legnaro, italy. high fold γ-γ coincidences were acquired with the 4π spectrometer gaspdetector array, consisting of 40 compton-suppressed, large-volume germanium detectors with an inn...

Fission fragment mass-angle correlations and mass ratio distributions have been measured for the reactions 16O+186Os, 24Mg+178Hf, 34S+168Er, and 48Ti+154Sm, forming the 202Po composite nucleus, at near barrier energies. Systematic analysis based on the expected dependence of the variance of the mass distribution on the angular momentum and temperature of the compound nucleus indicate that the t...

Microwave-assisted reactions are an environmentally friendly approach for synthesizing organic compounds. In this study, oximation of acetylferrocene and acetophenone was conducted under both microwave irradiation conventional heating conditions. Acetylferrocene were subjected to the two conditions in various solvent mixtures, extent conversion determined by 1H nuclear magnetic resonance spectr...

The surrogate reaction method may be used to determine the cross section for neutron induced reactions not accessible through standard experimental techniques. This is achieved by creating the same compound nucleus as would be expected in the desired reaction, but through a different incident channel, generally a direct transfer reaction. So far, the surrogate technique has been applied with re...

The astrophysical $S$ factor for the radiative proton capture process on $^{15}\mathrm{N}$ nucleus, i.e., $^{15}\mathrm{N}(p,\ensuremath{\gamma})^{16}\mathrm{O}$, at stellar energies are studied within framework of cluster effective field theory. thermonuclear $^{15}\mathrm{N}(p,\ensuremath{\gamma})^{16}\mathrm{O}$ reaction links type-I to type-II cycles carbon-nitrogen-oxygen cycle and affects...

Impairment of the dopaminergic system in the brain induced by dopamine-receptor antagonists or by specific neurotoxin terminal lesions results in motor disturbances in rats. In order to specify further the role of the different dopamine pathways in the brain on motor function, the performance of rats trained in an operant reaction-time task was examined after systemic administration of a dopami...
