Abstract

The invention relates to an electronic orbit radius measuring method and system based on an attosecond fringe spectrum, and a medium. The method comprises the following steps of acquiring the attosecond fringe spectrum generated when a plurality of infrared electric fields and a single attosecond pulse laser act on a working gas, and acquiring a plurality of classical fringe tracks generated whenthe plurality of infrared electric fields and the single attosecond pulse laser act on the working gas under a plurality of initial positions of electrons; obtaining a photoionization time delay of the working gas according to the attosecond fringe spectrum, and acquiring a plurality of classical photoionization time delays corresponding to the working gas according to the plurality of classical fringe tracks; and obtaining an electronic orbit radius corresponding to the working gas according to the photoionization time delay and the multiple classical photoionization time delays. Based on theattosecond fringe spectrum, the electronic orbit radius can be directly measured, a method and a theory are simple, calculating difficulty is low, a calculated amount is small, precision is high, anexisting bottleneck that the electronic orbit radius cannot be directly measured is broken through, and the method, the system and the medium have profound significance.

Description

technical field [0001] The invention relates to the technical field of microscopic particle measurement, in particular to an attosecond fringe spectrum-based electron orbital radius measurement method, system and medium. Background technique [0002] In 1913, Niels Bohr established the Bohr model describing the atomic structure. The model points out that electrons will only stay at certain distances (depending on energy) around the nucleus. For hydrogen atoms, there is only one electron orbit, which is the smallest orbit that electrons can move in hydrogen atoms, and its energy is The smallest, and the most probable distance for the hydrogen nucleus to find the smallest orbit is called the Bohr radius, that is, the radius of the electron orbit in the hydrogen atom is equal to the Bohr radius a 0 (approximately 0.529 Angstroms). [0003] Although the Bohr model cannot accurately describe the structure of an atom, the Bohr radius still has profound significance. On the one ...
