- Abstract
- The X-ray energies in the transitions to the ground state from the 2/sup 3//b P//sub 2/ and 2/sup 3//b S//sub 1/ levels in heliumlike phosphorus and from the 2/sup 4//b P//sub 5/2/ level in lithiumlike phosphorus have been determined by using a Doppler-tuned X-ray spectrometer. The experimental results /b E/(2/sup 3//b P//sub 2/-1/sup 1 //b S//sub 0/)=(2142.3+/-1.2) eV, /b E/(2/sup 3 //b S//sub 1/-1/sup 1//b S//sub 0 /)=(2126.7+/-1.2) eV, and /b E/(/sup 4//b P//sub 5/2/-/sup 2//b S//sub 1/2 /)=(2112.3+/-1.2) eV are in good agreement with theoretical predictions. The mean life of the 2/sup 4//b P//sub 5/2/ and 2/sup 3/P/sub 2/ states have also been measured by the beam-foil time-of-flight method. The experimental values tau (2/sup 3 //b P//sub 2/)=(3.6+/-0.1)*10/sup -9/ s and tau (2/sup 4//b P//sub 5/2/)=(1.2+/-0.1)*10 /sup -9/ s are in agreement with theoretical predictions.
