At temperatures below the depths of space just a few degrees above absolute zero researchers have replicated the universe’s ...

An international team led by the Universities of Geneva (UNIGE) and Montreal published the first results today from the NIRPS ...

This work demonstrated that ambient pressure X-ray photoelectron spectra of hydrogen and helium can be obtained when a bright-enough X-ray source is used, such as at the National Synchrotron Light ...

The measurement of the energy spectrum of cosmic ray helium nuclei from 70 GeV to 80 TeV using 4.5 years of data recorded by the DArk Matter Particle Explorer (DAMPE) is reported in this work. A ...

On the basis of stellar spectra totalling more than 200 hours of effective exposure time with the 8.2-m VLT Kueyen telescope at Paranal (Chile), a team of astronomers has made a surprising ...

Electron degradation and subexcitation spectra have been computed for helium gas containing a source of electron with initial energy of 1.99, 10, or 30 keV. The yield of primary ionizations was also ...

The team conducted laser spectroscopy experiments on muonic helium-3. Muonic helium-3 is a special form of helium in which the atom s two electrons are replaced by a single, much heavier muon.

While the Hubble Space Telescope only sees a narrow spectrum of visible light, Spitzer’s Infrared Array Camera, or IRAC, sees in the infrared, which is primarily heat radiation.

Feynman has recently advanced physical arguments to deduce an approximate form for the wave function of an elementary excitation in helium. Qualitatively, his theory leads to an excitation spectrum ...
