EXPERIMENTAL STUDIES OF PHOTON ABSORPTION IN SILICON AND NIOBIUM
Journal Title: Journal of Science And Arts - Year 2013, Vol 25, Issue 4
Abstract
The absorpt ion of photon through silicon and niobium is measured by using Si(Li) X - ray detector. We use Fe[sup]55[/sup] radioactive source to produce fluorescence lines from Si, Cl and Ti. The experimental results show that the absorption strongly depends on the energy of the i ncoming photon, material thickness and the atomic number of the absorber. The photon fraction absorbed is consistent when Nb and Si are placed together as an absorbing material and when they are placed one by one and resulting fraction is added. The experi mental results agree well with the calculated values of the photons fraction absorbed at five different energies.

A GENERAL EXPONENTIAL FAMILY OF ESTIMATORS FOR POPULATION MEAN USING AUXILIARY ATTRIBUTE
The present article addresses the problem of improved estimation of population mean of the study variable. For elevated estimation, we suggest a new generalized exponential ratio type family of estimators of population...
RHEOLOGICAL PROPERTIES OF MINERAL OIL
In this article presents us rheological behavior of mineral oil. Apparent viscosity of mineral oil was determined at temperatures between 400C-900C and shear rates ranging from 3.3-120s-1. This study is to find a polynom...
THE APROACH OF CLASSICAL COMPUTER TO QUANTUM COMPUTER
The aim of this paper is to guide computer scientists through the barriers that separate quantum computing from conventional computing. We introduce basic principles of quantum mechanics to explain where the power of qua...
