本文通过测量相对论重离子束的护航电子，研究了390 MeV/uAr ~（17+）离子穿过不同厚度碳膜时，相对论重离子与固体靶的相互作用。0°电子能谱由磁分析仪和耗尽层为5 mm的Si表面势垒探测器组合获得。实验室框架中的护航电子峰宽随着靶厚度从25 μg/cm 2增加到约500 μg/cm 2而减小，并且由于多次散射，靶越厚峰宽越宽。
Interactions of relativistic clothed heavy ions with solid targets have been studied for 390 MeV/u Ar17+ ions traversing carbon foils of various thicknesses through measurements of the convoy electrons. The electron energy spectra at 0° were obtained by a magnetic analyzer combined with a Si surface barrier detector with a depletion layer of 5 mm. The peak widths of the convoy electrons in the laboratory frame have been found to decrease as the target thickness is increased from 25 to about 500 µg/cm2, and broaden for thicker targets due to multiple scattering.
