Laser-assisted XUV Double Ionization of Helium: Energy-sharing Dependence of Joint Angular Distributions
By numerically solving the time-dependent Schrodinger equation in full dimensionality, we discuss the dependance of joint photoelectron angular distributions on the energy sharing of the emitted electrons for the double ionization of helium atoms by ultrashort pulses of extreme ultraviolet … Continue reading

Fast-rising Helium Prices May Pop Balloon Sales
In the midst of a national helium shortage, floating balloons serving as tokens of affection for Valentine’s Day can represent a precious commodity to business owners. Helium, the second most common element in the universe after hydrogen, is distilled during … Continue reading

Lawsuit Filed Against Navy for Destroyed Experimental Airship
The makers of a state-of-the art airship have filed a $65 million lawsuit against the U.S. Navy after the helium-filled dirigible was crushed when part of the roof of the hangar where it was stored collapsed on it. The suit, … Continue reading

Effect Of Helium Ion Beam Treatment On The Etching Rate Of Silicon Nitride
We investigated the effect of the helium ion implantation on the etching rate of silicon nitride in hydrofluoric acid. 30 keV helium ions were implanted into a 500-nm-thick silicon nitride film on silicon. Ion fluences from 1015 to 1017 cm−2 … Continue reading
