Optimization of measurement counting time in Gamma-ray spectrometry of soil samples
The method of optimal measurement counting time in Gamma spectrometry for soil samples was studied. Gamma spectrometry was done based on minimum detectable activity using the HPGe- p type with efficiency of 30% and FWHM 1.7keV (for 1.33 MeV 60Co). The samples were IAEA-RG Th-1, IAEA-RGU-1 and IAEA-RGK-1 prepared in bottles. The measurements were done for 12 different counting times from 5 min t...
متن کاملProducing 65Zn and 60Co gamma sources for energy and efficiency calibration of gamma spectrometry systems
Precise calibration of energy and efficiency of gamma spectrometry systems for different geometries is very important. In most cases, preparation of these sources for educational and research centers is very difficult due to high costs and lack of access to the reactor. The purpose of this paper is to explain the procedure for production of calibration sources 65Zn and 60Co using instrumental ...
متن کاملMeasurement of an Electronic Resonance in a Ground-State, Gas-Phase Acetophenone Cation via Strong-Field Mass Spectrometry.
A one-photon ionic resonance is measured in the strong-field regime in acetophenone by recording the mass spectra as a function of excitation wavelength from 800 to 1500 nm. The ratio of the benzoyl to parent ion signals in the mass spectrum varies significantly with excitation wavelength, where the highest ratio observed upon excitation at 1370 nm (0.90 eV) indicates the presence of a one-phot...
متن کاملMeasurement of conduction-electron polarization via the pairing resonance.
We show that the pairing resonance in the Pauli-limited normal state of ultrathin superconducting Al films provides a spin-resolved probe of conduction-electron polarization in thin magnetic films. A superconductor-insulator-ferromagnet tunneling junction is used to measure the density of states in supercritical parallel magnetic fields that are well beyond the Clogston-Chandresekhar limit, thu...
متن کاملSurface plasmon resonance monitoring of temperature via phase measurement
The application of surface plasmon resonance to the monitoring of the temperature of a metal film and its environment is well-established. A new feature in our present experimental work is to carry out this monitoring via the measurement of the phase difference between a s and a p-polarized wave at different wavelengths, 632.8 nm and 1.15 lm, based on a technique established previously in the l...
