Density shift and broadening of transition lines in antiprotonic helium.

Physical review letters

Bakalov D, Jeziorski B, Korona T, Szalewicz K, Tchoukova E.
PMID: 11018882
Phys Rev Lett. 2000 Mar 13;84(11):2350-3. doi: 10.1103/PhysRevLett.84.2350.

The density shift and broadening of the transition lines of antiprotonic helium have been evaluated in the impact approximation using an interatomic potential calculated ab initio with the symmetry-adapted perturbation theory. The results help to remove an uncertainty of...

Interpretation and implementation of an ion sensitive probe as a plasma potential diagnostic.

The Review of scientific instruments

Ochoukov R, Whyte DG, Lipschultz B, Labombard B, Wukitch S.
PMID: 21033976
Rev Sci Instrum. 2010 Oct;81(10):10E111. doi: 10.1063/1.3483192.

An ion sensitive probe (ISP) is developed as a robust diagnostic for measuring plasma potentials (Φ(P)) in magnetized plasmas. The ISP relies on the large difference between the ion and electron gyroradii (ρ(i)/ρ(e)∼60) to reduce the electron collection at...

Langmuir. 2014 Mar 25;30(11):3024-33. doi: 10.1021/la404825g. Epub 2014 Mar 11.

Drainage kinetics, thickness, and stability of water-in-oil thin liquid emulsion films obtained from asphaltenes, heavy oil (bitumen), and deasphalted heavy oil (maltenes) diluted in toluene are studied. The results show that asphaltenes stabilize thin organic liquid films at much...
