We present a simple numerical procedure for calculating the irrotational hydrodynamic flow around a spherical solute in superfluid helium. The results for alkali cations are compared to recent many-body variational Monte Carlo (VMC) calculations. The helium contribution to the effective masses calculated by the VMC and hydrodynamic methods are 12.9(4.6) versus 9.4 u for Li+, 48.2(5.6) versus 52...
متن کاملChemical trends for acceptor impurities in GaN
We present a comprehensive investigation of acceptor impurities in GaN, based on first-principles total-energy calculations. Two main factors are identified that determine acceptor incorporation: the strength of chemical bonding between the acceptor and its neighbors ~which can be assessed by comparison with existing compounds! and the atomic size match between the acceptor and the host atom fo...
متن کاملCurrent Trends in Leak Testing Technology
Leak detection techniques are not exclusively used for the vacuum products but are finding increasing applications in almost all industrial areas. Therefore, leak definition is evolving to accommodate the industry point of view. A leak always requires a flow of mass though the walls of a volume intended to be sealed. It usually results in escape or admission of liquids or gases from sealed comp...
متن کاملThe Chemical Evolution of Helium
We report on measurements of the He abundance toward the outer Galaxy H II region S 206 with the NRAO Green Bank telescope. Observations of hydrogen and helium radio recombination lines between 8 − 10GHz were made toward the peak radio continuum position in S 206. We derive He/H = 0.08459 ± 0.00088 (random)± 0.0010 (known systematic), 20% lower than optical recombination line results. It is dif...
