A STUDY AND ANALYSIS OF STOPPING POWER OF DIFFERENT PROJECTILES IN LANTHANIDES AND THEIR COMPOUNDS

Abstract

A comparative theoretical study of the stopping of different ions and their energy loss in the lanthanide elements and a few of their compounds (mainly oxides and halides) has been presented in this work. The ions that were used to achieve this were the light ion hydrogen, the alkali metal ion lithium, the non-metal ion oxygen, the alkaline earth metal calcium, the transition metals iron and gold, the post transition metal gallium, the metalloid arsenic and the noble gas argon. The values of the stopping were obtained from the software package SRIM2013 (Stopping and Range of Ions in Matter). The energy of the projectile has been varied from 10keV to 100MeV for the stopping in elements and from 10keV to 10MeV for the stopping in the compounds. The data obtained is rearranged in Microsoft Excel and Origin8 is used for plotting the graphs. An analysis is done for the different kinds of stopping i.e. electronic and nuclear stopping while the ion is traversing through the material. Also their variation along with different parameters is considered. The general inferences drawn from the different plots are mentioned in this work.
