Hydrogen Molecule Nuclei Image Is Obtained

German researchers have, for the first time, visualized vibration and rotation in the nuclei of a hydrogen molecule as a quantum mechanical wave packet. The scientists at the Max Planck Institute for Nuclear Physics in Heidelberg "photographed" the molecule using intensive, ultrashort laser pulses at different points and compiled a film from the separate images.

Since a hydrogen molecule is about 5,000 times smaller than the wavelength of visible light, it is impossible to create an optical image by photographing it. Instead, Max Planck researchers used pump-probe technology to make high-resolution and ultrahigh-speed images. The molecules are "bumped" with a "pump" laser pulse and measured with a "probe" laser pulse.

Using the technique, the scientists created the first complete image of the dynamic of one of the fastest molecular systems over a previously unachieved short time scale.

In the future, researchers say they will model the pump laser pulse to create a wave packet so certain quantum mechanical processes take place in preference to others.

The research appears in the online edition of Physical Review Letters.

Physicists Observe New Property of Matter

Los Angeles CA (SPX) Nov 06, 2006
Physicists at the University of California, San Diego have for the first time observed the spontaneous production of coherence within "excitons," the bound pairs of electrons and holes that enable semiconductors to function as novel electronic devices.
