Determination of potassium and sodium in an ash sample by gamma-ray spectroscopy

Neutron activation analysis and gamma-ray spectroscopy were used to determine the quantity of potassium and sodium in an ash sample of Tabebuia sp bombarded with thermal neutrons. These techniques, widely applied...

Upper limit on the thermal-neutron capture cross-section of⁴⁴Ti

A measurement of the thermal-neutron capture cross-section of⁴⁴Ti was performed. A sample of Sc₂O₃ was irradiated with protons to form⁴⁴Ti through the (p,2n) reaction. Later, the material was chemically treated a...

Decay scheme of^92m Nb

The beta decay of the 2^{+ 92m} Nb was reinvestigated via⁹³Nb(γ, n) reaction. The feeding of the 2⁺ 2,067 keV level of⁹²Zr was determined measuring the intensity of the 1,132 keV gamma-ray transition.

¹¹³In(γ, n) reaction isomeric and ground-state cross-sections

The¹¹³In(γ, n)¹¹²In^m,g reaction cross-sections were measured between 10 and 25 MeV. The measurements have been made by residual activity. A Lorentz line shape was fitted to the (γ, n) cross-section withE ₀=(16.8±...

Further studies on the charge-related alterations of methotrexate transport in Ehrlich ascites tumor cells by ionic liposomes: Correlation with liposome-cell association

Interaction of positively (phosphatidylcholine/stearylamine 5∶1) or negatively (phosphatidylcholine/stearic acid 5∶1) charged liposomes with Ehrlich ascites tumor cells for 1–5 min increases or decreases, resp...

Alterations of the carrier-mediated transport of an anionic solute, methotrexate, by charged liposomes in Ehrlich ascites tumor cells

Interaction of positively charged liposomes with Ehrlich ascites tumor cells increases the bidirectional transmembrane fluxes of the anionic folic acid analog, methotrexate. Negative liposomes reduce methotrex...

Gamma-ray transition between 9⁻ and 8⁻ levels in¹⁷⁸Hf measured in¹⁷⁸Ta 2.45 h decay

A gamma-ray transition in the decay of the¹⁷⁸Ta 2.45 h isomer with an energy of (216.7±0.1) keV and half-life (3±1) h was detected. This transition was interpreted as taking place between the 9⁻ and 8⁻ levels of^1...

Level scheme of¹²³Sb

Two new transitions in¹²³Sb from the beta decay of the 3/2⁺ ground state of¹²³Sn were found: one with (381.3±0.7) keV corresponding to (2.7±0.3)·10⁻²% of the disintegrations and one with (542.2±0.9) keV correspon...
