Electronic energy loss of channeled ions : the giant Barkas effect
(2004) [Artículo de periódico]In this work we have measured the electronic energy loss of ⁹Be and ¹¹B ions for the ‹100› and ‹110› directions in Si as a function of the incident ion energy. The channeling measurements cover a wide energy range between ... -
Electronic process implementation and organizational structuring
(2024) [Artículo de periódico]This article explores how a judiciary organization in Brazil underwent organizational change by implementing the virtualization of lawsuit processes. The virtualization of work processes requires practitioners to understand ... -
Electronic Stopping Power of /Sup 10/B in Si in Random and <100> Channeling Directions
(1997) [Artículo de periódico]We report measurements of 10B stopping powers in random and Si (100) directions. The measurements were carried out in the 500–9000 keV energy range for the channeling case and in the 300–800 keV for the random one. For the ... -
