摘要：
Experimental lifetimes of two 2p(5)3p and two 2p(5)3d levels of neonlike CrXV and FeXVII have been obtained using the beam-foil technique. Decay curves of the 3s-3p transitions were analyzed by the ANDC (Arbitrary Normalized Decay Curve) method taking into account cascading transitions from the 3d levels. Those of the 3p-3d transition were done by multi-exponential fitting. The lifetimes obtained in ns for the 3d(3)F(3) and 3d(3)F(4) levels are 0.136 and 0.117 for CrXV and 0.083 and 0.097 for FeXVII, and those of 3p(3)D(2) and 3p(3)D(3) are 0.208 and 0.171 for CrXV and 0.176 and 0.173 for FeXVII, respectively. The results are compared with theoretical values and the CrXV results are also compared with previous experimental work. Recent theoretical values agree well with the experimental values presented here.
