How can researchers employ the mechanism of photoionisation to gain an insight into complex molecular potential? This question has now been answered by a research team, led by Professor Dr Giuseppe Sansone,\u00a0from the Institute of Physics at the University of Freiburg.<\/a><\/p>\n The research team comprises of scientists from Freiburg, the Max Planck Institute for Nuclear Physics in Heidelberg, the Universidad Autonoma in Madrid, and the University of Trieste. Their results have been published in the journal Nature Communications.<\/em><\/p>\n In the origin of photoionisation, also named the photoelectric effect, an atom or molecule absorbs one quantum of light, usually indicated as photon<\/a>, from an external field. The energy absorbed in this process is transferred to an electron, which is liberated, leaving behind a singly charged ion.<\/p>\n In several aspects and for several applications, the impact can be regarded as instantaneous, meaning that there is no significant time delay between the absorption of the photon, and the instant when the electron is emitted.<\/p>\n However, several experiments conducted in the last couple of years have evidenced that tiny, yet measurable delays lying in the attosecond range (1 as=10-18 s), occur between these two processes.<\/p>\nPhotoionisation process<\/h3>\n
