The isospin dependence of the nucleus–nucleus inelastic cross-section at high energy

Calculation of the total cross section for the ionization of H, He, Ne and Ar atoms by bare ions at the high energy range

In the present work, the total cross-section for the ionization of  H, He, Ne and Ar atoms by +He2+ ، H+ ، Li3 ions has been calculated. In these calculations, a binary encounter approximation in the form of a two-body process between projectile ions and atomic electrons at the high energy range has been implemented. In order to enter the nuclear role of the target atom, the atomic electron vel...

Averaging of the inelastic cross-section measured

Energy dependence of nucleon-nucleon inelastic total cross-sections

Total inelastic pp cross-sections are reconstructed for laboratory kinetic energies ranging from 0.3 to 400 GeV. They are obtained by fitting together the sum of total cross-sections for exclusive inelastic channels, the sum of topological cross-sections and the results for independent « direct » measurements. The inelastic np cross-sections are reconstructed in the energy range below 4.2 GeV u...

the impact of musical texts on the text recall of young learners of english in isfahan junior high schools

abstract although music possesses some kind of power and using it has been welcome by many students in language classrooms, it seems that they take a non-serious image of the lesson while listening to songs and they may think that it is a matter of fun. the main objective of the present study was to investigate whether learning a foreign language through musical texts (songs) can have an impac...

the role of russia in transmission of energy from central asia and caucuses to european union

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
