Gamma Resonances near Threshold for the Production of Thermal Photoneutrons
Silviu Olariu, Agata Olariu
We have determined the positions of the (gamma,n) resonances and upper limits for the integrated cross sections for the (gamma,n) reactions, using data for the inverse process (n,g…
Incommensurate Spin Density Wave versus local magnetic inhomogeneities in Ba(Fe1-xNix)2As2: a 57Fe Mossbauer spectroscopy study
A. Olariu, P. Bonville, F. Rullier-Albenque +2
We report 57Fe Mossbauer spectral results in pure and doped Ba(Fe1-xNix)2As2 with x=0.01 and 0.03. We show that all these materials present a first-order magnetic transition toward…
Different effects of Ni and Co substitution on the transport properties of BaFe2As2
A. Olariu, F. Rullier-Albenque, D. Colson +1
We report resistivity and Hall effect results on Ba(Fe1-xNix)2As2 and compare them with those in Ba(Fe1-xCox)2As2. The Hall number RH is negative for all x values from 0.01 to 0.14…
Power densities for two-step gamma-ray transitions from isomeric states
Silviu Olariu, Agata Olariu
We have calculated the incident photon power density P_2 for which the two-step induced emission rate from an isomeric nucleus becomes equal to the natural isomeric decay rate. We…
Trace elements analysis of aerosol samples from some Romanian urban zones
I. V. Popescu, T. Badica, Agata Olariu +1
Aerosols deposits on filters from ten Romanian towns with different kinds and levels of industrial development have been studied. The concentration of elements with Z~16 have been…
Induced Emission of Gamma Radiation from Isomeric Nuclei
Silviu Olariu, Agata Olariu
We study the possibility to influence the lifetime of nuclear isomeric states with the aid of incident fluxes of photons. We assume that a nucleus initially in an isomeric state |i…
