The partitioning technique has been used to analyze the three and four electron systems into three-pairs electronic wave functions for Li-like ions (Li, Be⁺, B⁺⁺) and six-pairs electronic wave functions for Be-like ions (Li^-, Be, B⁺) by using Hartree-Fock wave functions of Clementi and Rotti.In this work the atomic scattering factor f(s) for K-shell and total atom for three and four electron systems are studied.

A series of sensors was developed to study the electromagnetic properties of a spark gap with various gaps between hm to 6mm. The gas used for the spark gap was air, at atmospheric pressure, ambient temperature ( 20°C ) and standard air composition. The sensors were developed to study the classical regions of the electromagnetic spectrum commonly called the visible, ultraviolet (W) , and near

This study is carried out to detect and measure the specific activities of radionuclides in cancerous samples of human tissues that excised from Baghdad city patients. The measurements were done using spectral analysis  technique for gamma-ray with 2"×2" NaI(Tl) scintillation detector.Our present investigations are based on the study of 24 abnormal samples and 8 normal samples for comparing the results. These samples include four types of fresh tissues (kidney, colon, breast, and uterus) that may be obtained with great mass.
