Abstract :
K X-ray photons of arsenic following orbital electron capture in Se75* radio isotope is been systematically measured by employing a simple nearly 2? – geometrical configuration. Characteristic K X-ray photons have been detected using a low energy Si (Li) detector and a PC based MCA. After suitable corrections, K X-ray intensity ratio of arsenic is calculated. Total vacancy transfer probability is computed from the former and fluorescence yield from Hubbell data tables. The K X-ray intensity of arsenic in the present work is compared with others’ values obtained by different techniques and with the theoretical values of Scofield. An uncertainty of less than 2% is been reported. The uncertainty is possibly due to the Coulomb exchange interaction amongst electrons involved in the shake-up process in the decaying nucleus.

Key-Words / Index Term :
K X-ray intensity ratio, 2?-geometry, total vacancy transfer probability.
