由于大量的电子捕获从富勒烯的分子壳通过传入的正电子弹丸和跨壳宽度的退相效应,正电子素形成信号在目标反冲动量空间中产生衍射条纹。我们的研究结果表明,在分离和形状的条纹图案作为富勒烯的大小的函数,从C 60到更大的C 240的方差。
Due to the bulk electron capture from the molecular shell of fullerenes by incoming positron projectiles and a dephasing effect across the shell width, the positronium formation signal yields diffraction fringes in the target recoil momentum space. Our results show the variance in the separation and shape of the fringe pattern as a function of the fullerene size from C 60 to larger C 240.
