Relativistic K shell decay rates and fluorescence yield for Fe

Kahoul, A; Kasri, Y; Sahnoune, Y; Deghfel, B; Khalfallah, F; Sampaio, J. M; Marques, J. P (Université Frères Mentouri - Constantine 1, 2016-12-15)

In this work, we derive the K-shell fluorescence yield using a Dirac-Fock model. To compute, radiationless and radiative transition rates we have used the MCDF code of Desclaux and Indelicato [1- 3]. The wave functions ...
Relativistic calculations of K-shell photoionization cross-sections for 16 𝟑𝟐 𝐒 at 59.6 keV excitation energy

Khalfallah, F; Kahoul, A; Kasri, Y (Université Frères Mentouri - Constantine 1, 2016-12-15)

In this work we calculate photoionization X-ray cross-sections of K-shell vacancies in S at incident photon energy of 59.6 keV using the Dirac-Fock method and the MCDFGME (Multi Configuration Dirac Fock and General Matrix ...
Calculations of Maxwellian Averaged capture Cross Sections Using the ENDF/B- VII.1, KADONiS, EXFOR and JEFF-3.1 evaluated nuclear reaction data libraries

Djerboua, Y; Amrani, N; Boucenna, A (Université Frères Mentouri - Constantine 1, 2016-12-15)

We calculate the Maxwellian-averaged cross sections (MACS) of the stellar nucleosynthesis reactions (n,g ) using the ENDF/B-VII.1, KADONiS, EXFOR and JEFF-3.1 evaluated nuclear data libraries. The calculated capture cross ...
New calculation of L1 subshell yields fluorescence of heavy elements

Sahnoune, Y; Kahoul, A; Kasri, Y; Deghfel, B; Medjadi, D.E (Université Frères Mentouri - Constantine 1, 2016-12-15)

The analytical methods based on X-ray fluorescence have a great importance for a number of practical applications in a variety of fields including atomic physics, X-ray fluorescence surface chemical analysis, medical ...
Inflationary models and applications

Djeha, K; Si Lakhal, B (Université Frères Mentouri - Constantine 1, 2016-12-15)

Study the cosmic microwave background: polarization and anisotropy.The inflationary model has been proposed to address the shortcomings of the standard model of cosmology. This cosmological model offers both a solution ...
Dose Evaluation in adaptive radiotherapy in head and neck cancers

Chibane, B. I; Benrachi, F; Bali, M.S (Université Frères Mentouri - Constantine 1, 2016-12-15)

Recent developments in radiotherapy techniques, particularly VMAT technique is a tool of choice in the treatment of tumors with complex shapes such as head and neck cancers. Patients with head and neck cancer are prone ...
The numerical study of the origin of the ultra high energy cosmic rays with CRPropa

Bouchachi, D; Attallah, R (Université Frères Mentouri - Constantine 1, 2016-12-15)

The origin of ultra-high-energy cosmic rays is one of the most enigmatic questions in modern physics. The study of a such high-energy particles is a new and active research area where scientists wish to find the still-unknown ...
Nuclei structure around shell closure N = 82

Kaim, S (Université Frères Mentouri - Constantine 1, 2016-12-15)

The nuclei with A=140 having a few holes in the N =82 shell closure offer a fertile region to investigate the shape evolution. They are spherical or only slightly deformed in the ground state and at small angular momenta, ...
Path Integral Solution of a Singular Oscillator Potential

Bekhouche, S; Bentag, B (Université Frères Mentouri - Constantine 1, 2016-12-15)

By path integral formulation and delta functional technics we calculated the propagator of singular oscillator. We have foundthe discrete spectrum and the corresponding wave functions
On Yang-Mills Matrix Models: Emergent Geometry

Ramda, K (Université Frères Mentouri - Constantine 1, 2016-12-15)

One of the most fundamental questions we can ask about a given gauge theory is its phase diagram. We present Monte Carlo simulations, for a simple three matrix model that exhibits an exotic phase transition. we focus on ...
BaTiO3-TiO2 nanotubesproduced by classical hydrothermal methodand their photoelectrochemical properties

Sobti, N; Kendouli, S; Baghriche, M; Achour, S (Université Frères Mentouri - Constantine 1, 2016-12-15)

Nanotubes are of great interest due to their high surface-to-volume ratios and size-dependent properties. Titanium dioxide nanotube array is a well-known nanostructured semiconductor oxide with improved functional ...
A Study of the structural and electronic properties of LaX (X=Se, Te ) in two phases B1, B2 ander high pressure

Soltani, F; Baaziz, H; Charifi, Z (Université Frères Mentouri - Constantine 1, 2016-12-15)

The objective of this work is a study of the structural properties (lattice parameters, total energy, bulk modulus) and electronic properties (band structure, density of states) of rare earth monochalcogenides LaX (X=Se, ...
Behaviour of dislocations near phase boundaries inbicrystals of FCC materials: Au-X, X = Pb, Cu and Ni

Ouchtati, A; Khalfallah, O (Université Frères Mentouri - Constantine 1, 2016-12-15)

The mechanical properties of materials are determined by the interactions between defects found in the crystal. In a bicrystal of bimaterials, the result forces exercising on the matrix dislocation near and parallel to an ...
