Fig. 1: Breakup on three pathways. A hydronium ion captures an electron and can then split into different combinations of fragments. The relative yields of the three pathways are shown as measured for the heavy hydronium ion D3O+. The capture produces the unstable radical D3O with the captured electron in a weakly bound (Rydberg) state.

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).
