We have used a combination of stellar population synthesis and photoioniza-tion models to develop a set of ionization parameter and abundance diagnostics based only on the use of the strong optical emission lines. These models are applicable to both extragalactic H II regions and star-forming galaxies. We show that, because our techniques solve explicitly for both the ionization parameter and t...

On April 9 2015, the Letter article titled "Measurement of the first ionization potential of lawrencium, element 103" is now published at News and Views on Nature (2015) which has been performed by our remarkably Japanese colleagues of nuclear and radiochemistry at JAEA (Japan Atomic Energy Agency). In this review, the author will state that the isotope separator on-line (ISOL) our regularly us...

The recent development of techniques for laser-driven shock compression of hydrogen has opened the door to the experimental determination of its behavior under conditions characteristic of stellar and planetary interiors. The new data probe the equation of state (EOS) of dense hydrogen in the complex regime of pressure ionization. The structure and evolution of dense astrophysical bodies depend...

We have run a set of experiments in the CLOUD chamber at CERN, Switzerland, studying the effect of dimethylamine (DMA) on sulfuric acid (SA)-water nucleation using a nitrate based Chemical Ionization Atmospheric Pressure ionization Time-Of-Flight Mass Spectrometer (CI-APiTOF). Experiment was designed to produce neutral high m/z SA-DMA clusters in close to atmospherically relevant conditions to ...

The combination of mass spectrometry imaging and histology has proven a powerful approach for obtaining molecular signatures from specific cells/tissues of interest, whether to identify biomolecular changes associated with specific histopathological entities or to determine the amount of a drug in specific organs/compartments. Currently there is no software that is able to explicitly register m...

2014 We explain that the temperature coefficient of the ionization energy of a deep level can be determined from measurements of carrier emission rate and capture rate, using transient capacitance techniques such as DLTS. Two electron traps and three hole traps in GaAs are examined as an illustration. One of the hole traps appears to be strongly pinned to the conduction band. LE JOURNAL DE PHYS...

Muon beam ionization cooling is a key component for the next generation of high-luminosity muon colliders. To reach adequately high luminosity without excessively large muon intensities, it was proposed previously to combine ionization cooling with techniques using a parametric resonance (PIC). Practical implementation of PIC proposal is a subject of this report. We show that an addition of ske...

the ionization effects of charged particles produced in neutron interactions for boron neutroncapture therapy are considered here using srim monte carlo code. the estimated values of these effects ina plexiglas acrylic phantom are shown to agree well with the available experimental values in high boronconcentration areas. as expected, the ionization effects from lithium and alpha particles are ...
