Abstract
The decay of the 1s(2)2s3pP-3(0, 1, 2)o levels in Be-like ions of Na, Mg, Al and Si has been investigated using the beam-foil method. The me an wavelengths of the transitions 1s(2)2p2P-3(0, 1, 2)-1s(2)2s3p P-3(0 , 1, 2)o and the lifetimes of the 1s2(2)s3pP-3(0, 1, 2)o levels have b een measured. An intercomparison of these lifetimes yields the transit ion probability of the intercombination line 1s(2)2s2S-1(0)-1s(2)2s3pP -3(1)o. The results are (3.45 +/- 0.73) 10(9) s-1 in Na VIII, (5.55 +/ - 0.96) 10(9) s-1 in Mg IX, (1.21 +/- 0.24) 10(10) s-1 in Al X and (2. 50 +/- 0.54) 10(10) s-1 in Si XI.
