High-energy break-up of 6Li as a tool to study the Big-Bang nucleosynthesis reaction 2H(alpha,gamma)6Li
High-energy break-up 6Li tool study the Big-Bang nucleosynthesis reaction 2H(alpha,gamma)6Li
2010/12/31
The recently claimed observations of non-negligible amounts of 6Li in old halo stars have renewed interest in the Big-Bang Nucleosynthesis (BBN) of 6Li. One important ingredient in the predicted BBN a...

Gamma Radiation Measurement System Marine Sediment Rock Analysis
2010/11/16
A new high-efficiency and low-background system for the measurement of natural gamma radioactivity in marine sediment and rock cores retrieved from beneath the seabed was designed, built, and install...
Method for Creating and Detecting Hydrogen Sorption Sites Using Gamma Radiation
Hydrogen Sorption Sites Gamma Radiation
2010/11/12
Using gamma radiation and volumetric analysis of desorbed gas, hydrogen gas bonding sites have been created and detected in select materials. Desorption of hydrogen was followed over a benign tempera...
We present a study of the inclusive photon spectra from 5.9 million J/psi decays collected with the KEDR detector at the VEPP-4M e+e- collider. We measure the branching fraction of radiative decay J/p...

The level structures of neutronrich 105Mo, 106Mo, 108Mo and 110Ru nuclei in A ≈ 100 region have been carefully investigated by coincidence measurements of the prompt γrays populated in the spontaneo...
Analytical and statistical calculation of gamma dose rate for the accident of losing the shield for Tehran Research Reactor
TRR gamma-ray dose rate MCNP4C
2009/8/17
In this paper we study the analytical and statistical results of estimating the gamma dose rate at pool access floor in TRR when the core shield accidentally decreases to some non-permitted levels. Du...
