K-BETA K-ALPHA X-RAY-INTENSITY RATIO IN THE REGION OF -LESS-THAN-OR-EQUAL-TO-Z-LESS-THAN-OR-EQUAL-TO-22/

The X-ray intensity ratio K-beta/K-alpha,has been measured by using a 10 mCi Fe-55 source (Mn K X-rays) and high resolution Si(Li)detector s ystem coupled to a computer-controlled multichannel analyzer over the range of 15 less than or equal to Z less than or equal to 22. Correcti ons have been made to the measured relative intensities (K-alpha and K -beta X-rays) for self-absorption in the sample, air, Be-window absorp tion and detection efficiency. The results are compared with those of other experiments and with the Scofield calculations.
