“…significantly large deviations are noticed. Further, it is interesting to mention that our calculations normally provide close agreement with the most recent experimental data [43] for C, O, Mg and Al ions in Ti absorber (Figs. 5-6) in the energy range≈ 0.2-0.5MeV/n.…”

The energy loss for swift heavy ions, covering Z=3-29(~0.2 - 5.0MeV/n), has been calculated in the elemental absorbers like C, Al and Ti. The present calculations are based on Bohr’s approach applicable in both classical and quantum mechanical regimes. The major input parameter, the effective charge, has been calculated in a different way without any empirical/semi-empirical parameterization. The calculated energy loss values have been compared with the available experimental data which results in a close agreement.

“…Even though more than a century of extensive investigation has passed, the process of energy loss 3 still configures an active field in modern science and technological applications. Precise and quantitative measurements with ion beams are required in material science and engineering [9,10,11,12], medical physics (radiotherapy) [13], ion implantation and modification of materials [14], and also in practically all Ion Beam Analysis (IBA) techniques [15,16,17,18,19,20]. Current research may be divided in two main categories: i) measuring accurate and reliable stopping power data, and ii) improving fundamental physics models, in other words: stopping power is a prerequisite for precise validation of theoretical models.…”

The phenomenon of energy loss that occurs when an ion interacts with matter, also called stopping power, has been investigated for more than a century, and has provided findings of interest. However, reliable procedures for obtaining accurate experimental measurements and a fully theoretical comprehension of the process are tasks still in high demand by the scientific community. Moreover, stopping power data are prerequisites in several applications in modern science, such as engineering, ion implantation and modification of materials, damage to electronics devices (e.g. space radiation), medical physics (e.g. proton therapy), among others. In this thesis we i) develop a rigorous experimental protocol to measure stopping power with high precision, and ii) investigate 1 the collapse of the free electron gas (FEG) model in energy loss of light ions (protons) at a low energy range in transition and rare-earth metals. In the first part, we present an approach to obtain, with high accuracy, the stopping cross sections in the pure materials Al and Mo for protons in the energy range of [0.9 − 3.6] MeV by means of the transmission method. The traceability of the sources of uncertainties are fully evaluated and the final accuracy of the results is 0.63 % (0.32 % rand. and 0.54 % syst.) for Al, and 1.5 % (0.44 % rand. and 1.4 % syst.) for Mo, with both results primarily limited by the quality and homogeneity of the stopping foils. For Al, this high accuracy represents an improvement com-Foremost I want to express my gratitude to my advisor, co-author and friend Prof. Dr. Manfredo H. Tabacniks. His guidance, encouragement over the years, vast scientific knowledge and notable vision in many other areas (e.g. ethics and interaction with participants) have always inspired me to reach interesting findings in physics and in life, always expanding my mind. Without his support, the accomplishments here presented would never have been possible. Thank you so much.
