✦ Synopsis

The L subshell fluorescence yields x 1 , x 2 and x 3 have been measured in the range 45 6 Z 6 50 by exciting the elemental targets with a synchrotron radiation beam at 7 keV. The characteristic L X-ray photons originating from the targets are measured with a Si(Li) detector. The L shell fluorescence yields have been determined using the experimental L a , L b1 , L b2 , L c1 and (L c2 + L c3 ) X-ray production cross sections, the theoretical L subshell photoionization cross sections, the Coster-Kronig transitions yields and the fractional X-ray emission rates. The measured values of x 1 , x 2 and x 3 are compared with theoretical values and with semi-empirical compilations data.
