Image for: On quantum paths through the helium atom


Ionization of helium in an ultra-short laser pulse. The electron is launched from the atomic potential (blue funnel) at t1 or t2, i. e. at the maxima of the electric field amplitude (yellow curve). Both paths sample the parent ion differently. The corre-sponding wave packets of the escaping electron are finally superimposed (right) leading to interference.

Search / advanced search of the idw archives
Combination of search terms

You can combine search terms with and, or and/or not, e.g. Philo not logy.

Brackets

You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).

Phrases

Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.

Selection criteria

You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).

If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
