Stopping Power Calculations for Heavy Relativistic Ions
Recent theoretical results have led to improvements in formulas for dE=dx, particularly in the regime of high projectile charge and moderate to highly relativistic velocities. In addition, integration of dE=dx leads to predictions of total range given initial energy and, reciprocally, initial energy given total range. We have compiled theoretical formulas for dE=dx from a variety of sources int...
متن کاملStopping Powers of Protons in Biological Human Body Substances
In this paper we present a simple method for the calculation of mass stopping power (in MeV cm/g) of protons from 0.5 Mev to 200 MeV energy range in biological human body substances such as water, bone, muscle and tissue. The proposed relations have been described in terms of energy of proton and mean () of atomic number (Z) and atomic weight (A). A fairly good agreement has been found bet...
متن کاملQuantum mechanical proton range in human body
Introduction: Proton therapy delivers radiation to tumor tissue in a much more confined way than conventional photon therapy thus allowing the radiation oncologist to use a greater dose while still minimizing side. Materials and Methods: protons release most of their energy within the tumor region. As a result, the treating physician can potentially give an...

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولStopping of Protons - Improved Accuracy of the UCA Model
Recent theoretical developments in the unitary convolution approximation (UCA) for electronic energy losses of bare and screened ions are presented. Examples are given for proton beams and rare-gas targets. For gas targets there exists a sufficient amount of experimental data on charge exchange, for pinpointing the largely unknown stopping-power contribution of electron-capture processes at low...
