Bestimmung der absoluten Übergangswahrscheinlichkeit der Linie C II 2511 Å

Determination of the absolute transition probability of the line CII 2511 Å

  • Published:

Abstract

The transition probability of the CII line 2511 Å has been determined from relative intensity measurements of singly ionized carbon lines calibrated by the life time value of the 42 F 0-level obtained by the beam-foil method. The spectra were exposed from a quasistationary pulsed discharge between carbon electrodes in a helium-hydrogen mixture. Assuming LTE Saha's equation for C III/C II yielded the plasma temperature while the electron density was determined from theH β profile. The transition probability of the line CII 1 324 Å was evaluated by the aid of the well-known life time of the2 D 0-level.
