POSTDOCTORAL POSITION
(EXPERIMENTAL CHEMICAL PHYSICS)
A postdoctoral position has become immediately available in my laboratory.
Project: Spectroscopy of Molecules in Cold Helium Droplets
Nano-droplets of about 10000 helium atoms are produced in a cold molecular
beam
source and doped with foreign atoms or molecules. The atoms or molecules can
form aggregates or react in cold collisions within the “helium trap” and are
spectroscopically studied by using various laser techniques. Currently,
high-resolution laser double resonance and resonant multiphoton ionization
spectroscopy can be applied.
The apparatus is complete and produces immediate results.
The investigation of doped helium nano-droplets represents an exciting new
area
of research. The droplets are possibly a finite-size superfluid medium.
Moreover, the “helium nano-cryostats” of 0.4 Kelvin temperature offer an ideal
environment for the study of
1. cold collisions,
2. cold molecular reactions,
3. large molecules with dense spectra including biologically important
species,
4. the aggregation of metal atoms (preparation of nanostructures).
Applicants should have an excellent record of PhD research and have
experience
with molecular beams and some laser spectroscopic methods. A background in
chemical physics and high-resolution molecular spectroscopy will be
particularly useful. The appointment is initially for one year and can be
renewed. The salary will be commensurate with qualifications. The appointment
can start at any time between now and fall of 1999.
Applications and two letters of recommendation should be sent to
Professor Wolfgang E. Ernst
