Study of CK Enhancement Factors for Oxygen Induced L Subshell X-rays in Lanthanum Series (58 ≤ Z ≤ 70)

Abstract

CK Enhancement Factor (kα,l, kβ and kγ) has been studied for Lanthanum series (58 ≤ Z ≤ 70) with oxygen as projectile in the energy range of 1.5 - 3.5 MeV. It is observed that by changing projectile energy, there is a change in enhancement factor for all the elements. While studying the variation of enhancement factor with atomic number (Z) and the energy of projectile element, it is found that there is an irregular trend in the variation of enhancement factor. The maximum value of enhancement factor is 2.3126 in Nd (Z=60) at 1.5 MeV energy. In all the elements there is a decrease in the enhancement factor with increase in energy of projectile. The value of kα,l enhancement factor is found to be maximum in all cases followed by kβ and kγ.
