The steady-state nucleation rate and flux of composite nucleus at the saddle point is studied by extending the theory of binary nucleation. The Fokker-Planck equation that describes the nucleation flux is derived using the Master equation for the growth of the composite nucleus, which consists of the core of the final stable phase surrounded by a wetting layer of the intermediate metastable pha...
We review some salient aspects of calculations of the neutrino-nucleus reaction cross sections in the low energy range (1-100 MeV).

The determination of nuclear structure parameters such as gamma transitions, level scheme, density and radiative strength functions is one the most important tasks in low-energy physics. two-step cascades method based on detection coincidences following neutron capture, ie. (n,2γ) reaction has been proven to give spectroscopic data concerning function. This allows for study dynamics interaction...
In the Surrogate Method, the measured decay probability of a compound nucleus formed via a direct reaction is used to extract the cross section for a reaction with a different entrance channel that proceeds through the same compound nucleus. An extension of the Surrogate Method, the Surrogate Ratio Method (SRM), uses a ratio of measured decay probabilities to infer an unknown cross section rela...
Silica-supported oxovanadium groups were reacted in a gas-solid reaction with aniline at 175 degrees C. The reaction was clean as monitored in situ by UV-vis spectroscopy and resulted in the elimination of water as the principal product of the reaction and the disappearance of the terminal V=O stretch in the Raman spectrum. 15N MAS solid-state NMR spectroscopy showed only a single nitrogen-cont...
The neutron capture cross sections of 107 Pd were measured using the Accurate Neutron-Nucleus Reaction Measurement Instrument (ANNRI) at Japan Proton Accelerator Research Complex (J-PARC). Capture γ-rays detected with a NaI(Tl) spectrometer. incident energy was determined by time-of-flight method. preliminary section derived from thermal to resonance region. In region, parameters analysis REFIT ...
We present the results of our calculation which has been performed to study the nuclear effects in the quasielastic, inelastic and deep inelastic scattering of neutrinos(antineutrinos) from nuclear targets. These calculations are done in the local density approximation. We take into account the effect of Pauli blocking, Fermi motion, Coulomb effect, renormalization of weak transition strengths ...
