We present a theoretical study on formation rates of η and ω meson-nucleus systems induced by (γ, p) reactions on nuclear targets at ideal recoilless condition. We find that the smaller distortion effect in the (γ, p) reaction enables us to investigate properties of the mesons created deeply inside nucleus more clearly. We also consider excitation of scalar-isoscalar (σ) mode in nucleus in orde...

Nucleus replacement technologies are a minimally invasive alternative to spinal fusion and total disc replacement that have the potential to reduce pain and restore motion for patients with degenerative disc disease. Finite element modeling can be used to determine the biomechanics associated with nucleus replacement technologies. The current study focuses on a new nucleus replacement device de...

in the present research, we want to simulate the fission process of the excited nucleus 207at produced in fusion reaction 19f+188os in the framework of the modified statistical model with considering the effects of projection of spin about the symmetry axis, k, and temperature. in our simulation, we calculate the fission cross section and anisotropy of the fission fragment angular distribution ...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
The elastic scattering cross section measured at energies $E\lesssim 10$ MeV/nucleon for some light heavy-ion systems having two identical cores like \oc exhibits an enhanced oscillatory pattern the backward angles. Such a is known to be due transfer of valence nucleon or cluster between cores. In particular, $\alpha$ has been shown originate directly from core-exchange symmetry in scattering. ...
It has been suggested that the caudate nucleus, the input stage of the basal ganglia, facilitates and suppresses saccade initiation based on its anatomical characteristics. Although the involvement of the caudate nucleus in saccade facilitation has been shown previously, it is still unclear whether the caudate nucleus is also involved in saccade suppression. Here, we revealed the direct involve...
Transverse momentum spectra of ?+, p, ?, ? or ?¯+, ? ?¯+ and deuteron (d) in different centrality intervals nucleus–nucleus collisions at the center mass energy are analyzed by blast wave model with Boltzmann Gibbs statistics. We extracted kinetic freezeout temperature, transverse flow velocity volume from particles. It is observed that non-strange strange (multi-strange) particles separately d...
The differential cross sections of the forward coherent $\omega$ and $\phi$ mesons photoproduction from nuclei have been calculated using Glauber model for nuclear reaction. measured section elementary reaction, i.e., $\gamma N \to \omega (\phi) N$ are used as input in model. experimentally determined free-space scattering parameters quoted to evaluate meson nucleus interactions. sensitivity Fe...
