Investigation on optical properties in the surface of KClxBr1-x mixed crystals irradiated to gamma radiation (A new approach)
Background: Similar to the thermoluminescence (TL) spectra, the optical parameters variations can also be used in TL crystals for dosimetry purposes. These optical parameters can include absorption, transmission and reflection coefficients. Materials and Methods: Single crystals of KBr and KCl which have been used in this research were grown from laboratory grade extra pure precursor p...
متن کاملSTUDY OF NUCLEAR LEVEL DENSITY AND SPIN CUT-OFF FACTORS
Nuclear level densities and spin cut-off factors have been deduced for nuclei in the mass region 24‹A‹63,from a microscopic theory, which includes nuclear pairing interaction. Single particle levels for both Seeger and Nilsson potentials were used in the calcdations. Level densities extracted from the theory are compared with their conesponding experimental values, It is found that the overall...
متن کاملMEASUREMENT OF DEUTERON SPIN RELAXATION TIMES IN LIQUID CRYSTALS by a BROADBAND EXCITATION SEQUENCE
Liquid crystals are composed of flexible organic molecules and capable of forming different ordered structures in their mesophases. Nuclear spin relaxation [1], [2] is a powerful technique that provides useful information on the molecular dynamics of liquid crystals. There are collective director fluctuations, molecular reorientation and internal rotations in flexible end chains. Recently inter...
متن کامل17O and 51V NMR for the zigzag spin-1 chain compound CaV2O4
51V NMR studies on CaV2O4 single crystals and 17O NMR studies on 17O-enriched powder samples are reported. The temperature dependences of the 17O NMR linewidth and nuclear spin-lattice relaxation rate give strong evidence for a long-range antiferromagnetic transition at TN=78 K in the powder. Magnetic susceptibility measurements show that TN=69 K in the crystals. A zero-field 51V NMR signal was...
متن کاملModeling and Simulation Research on Dynamics of Missiles with Deflectable Nose Control
The dynamic characteristics of deflectable nose missiles with rotary single-channel control were investigated in this paper. Firstly, the effective angle of attack, effective angle of sideslip and quasi-body coordinates were introduced based on the spin characteristics of the missile’s body. Secondly, considering the interaction between the missile’s nose and body, the rigid kinetic model of mi...
