| Abstract: | Transition probabilities of 211 spectral lines of VII, in the wavelength range 2340–4200 Å, have been determined by emission spectroscopy using a wall-stabilized arc as source. The lines studied belong to the transition arrays 3d4, 3d34s-3d34p (199 lines) and 3d34p-3d34d, 3d35s (12 lines). Vanadium was introduced into the helium-arc discharge as the liquid VOCl3. An important feature of this work is the determination of transition probabilities for many lines from a wide spectral range with a uniform absolute scale. The absolute Aki values were obtained by normalizing relative Aki values to an absolute scale set by ionic lifetime for the level y3H04. These results are compared with other experimental as well as theoretical results. |
