Constants of quenching of 5s 22 D 5/2, 3/2 CdII levels by argon

A. I. Mis’kevich, Xiaolin Zhao

Constants of quenching of the CdII ion Beutler levels by argon were experimentally determined. Excited cadmium ions in the 5s 2 2 D 5/2, 3/2 states were produced by sputtering metal cadmium with alpha-particles at a temperature of 240°C. The quenching constants for the 5s 2 2 D 5/2 and 5s 2 2 D 3/2 CdII ion levels were found to be 1.3×10−10 and 1.8×10−10 cm3 s−1, respectively.

Pulsed metastable atomic beam source for time-of-flight applications

Armin KOHLHASE, Shigetomo KITA

A metastable atomic beam source was developed utilizing pulsed helium and argon nozzle beams. A coaxial electron gun, which can be used in a pulsed as well as in a continuous mode, excites the noble gases to their metastable states by electron bombardment in the direction of propagation of the ground-state atoms. In contrast to former work, the electron beam is controlled and accelerated by a combination of three hemispherically shaped tungsten grids. With continuous electron gun operation the source produces a metastable flux of about 1015 atoms/sr s for helium and argon under optimum expansion conditions. Applying short electrical pulses to a control grid yields supersonic metastable atom pulses, with velocity distributions having a relative width as low as 3.8% for helium and 6.5% for argon ( FWHM ) with a 100% modulation of the metastable beams. These features make the source applicable for velocity analyzed scattering experiments using the time-of-flight technique.
