论文摘要
如今，为了研究半衰期很短的核，需要强烈的外来梁。为了提高裂变产物的释放效率，必须改善所涉及的所有目标特征（例如化学成分，尺寸，物理化学特性，例如晶粒尺寸，孔隙率，密度等）。在本文中，我们研究了目标厚度的影响。提出了从石墨和碳化铀颗粒测量的释放部分，以及布朗运动的蒙特卡洛模拟。
Nowadays, intense exotic beams are needed in order to study nuclei with very short half-life. To increase the release efficiency of the fission products, all the target characteristics involved must be improved (e.g. chemical composition, dimensions, physicochemical properties such as grain size, porosity, density etc). In this article, we study the impact of the target thickness. Released fractions measured from graphite and uranium carbide pellets are presented as well as Monte-Carlo simulations of the Brownian motion.
