Collectivity and configuration mixing in 186,188Pb and 194Po.

A Numerical Study on Mixing of Transverse Injection in Supersonic Combustor

A numerical study on mixing of hydrogen injected transversely into a supersonic air stream has been performed by solving Two-Dimensional full Navier-Stokes equations. An explicit Harten-Yee Non-MUSCL Modified-flux-type TVD scheme has been used to solve the system of equations, and a zero-equation algebraic turbulence model to calculate the eddy viscosity coefficient. The main objectives of this...

Nontrivial aspects of the onset of nuclear collectivity: Static moments.

We consider several topics concerning static magnetic dipole and electric quadrupole moments (μ and Q) as signatures of the onset of nuclear collectivity. Having previously noted that in Cr there is an abrupt change of sign in Q of yrast states with J = 10, 12, and 14 relative to lower J states, we discuss whether these states are oblate or prolate. We next show that configuration mixing leads ...

Collectivity in Heavy Nuclei in the Shell Model Monte Carlo Approach

The microscopic description of collectivity in heavy nuclei in the framework of the configuration-interaction shell model has been a major challenge. The size of the model space required for the description of heavy nuclei prohibits the use of conventional diagonalization methods. We have overcome this difficulty by using the shell model Monte Carlo (SMMC) method, which can treat model spaces t...

رفتار نورشکستی بلور تیتانات باریم و کاربردهای آن در اندازه گیریهای اپتیکی در زمان واقعی

In this research we measure some of the optical parameters of Barium Titanate crystal (BaTiO3), such as signal beam gain, coupling constant (exponential gain coefficient), change in index refraction and photorefractive sensitivity, which are very significant for optical data storage. In all experiment, two- wave mixing configuration at 632.8 nm (He- Ne laser) were used. Experimental data f...
