Investigation of Fractals on Aluminium Foil Irradiated by Intense Relativistic Electron Beams

A lot of work has been done on fractals. However, few reports are onfractal pattern induced by electron beams. In this note, we report an experimentalphenomenon on fractals that appear on aluminium foil irradiated in vacuum by in-tense relativistic electron beams, and investigate the characteristics of the fractalstructure.
