Tidskriftsartikel (refereegranskat)abstract
- By pulse modulating or deflecting a CW dye laser beam, cascade-free lifetime determinations at high spectral resolution can be performed with the decayed-coincidence technique using measuring times of about 1 minute. The method is illustrated by lifetime measurements for the 72P3/21/2 levels of cesium.

- It is inferred from a model calculation that, to a very good approximation, the XPS spectra from core electrons in simple metals should follow the edge power law up to the first plasmon satellite. The power law indices obtained are in good agreement with recent experimental XPS values for Na, Mg and Al.(9 refs)

- Landé gJ factors are determined for the three lowest 2P levels in the Cs atom from measured level crossing positions together with a factors determined by zero field double resonance. The hyperfine anomalies between 133Cs, 135Cs and 137Cs are discussed.

Positron annihilation rate for a low density electron gas
- 1976
-
Ingår i: Physics Letters, Section A: General, Atomic and Solid State Physics. - 0375-9601. ; 57:1, s. 35-37
-
Tidskriftsartikel (refereegranskat)abstract
- A simple approach, which utilizes existing results for the electron density around a fixed attractive point charge in an electron gas, is presented for treating the annihilation rate of a positron in an electron gas at low density.
