A postdoctoral fellowship is available in the laboratory of Dr. David W.
Chandler of Sandia National Laboratory in Livermore, Ca. The research is
in the area of cooling of molecules to sub Kelvin temperatures by single
collisions in a crossed molecular beam apparatus. The first results have
recently been published in Science. By controlling a collision between a
nitric oxide (NO) molecule and an argon (Ar) atom we have been able to slow
the NO molecules in the J=7.5 rotational state to speeds that correspond to
temperatures of less than 400 millikelvin (0.4K), or speeds less than 15
meters/sec ("Subkelvin cooling of NO molecules via "billiard-like"
collisions with argon" Science, M. S. Elioff, J. J. Valentini and D. W.
Chandler, Vol. 302, pp. 1940-1943 (2003)). This postdoctoral fellowship is
to continue this research with the goal of trapping molecules for further
cooling and the study of collisional energy transfer at very low collision
energies.
Required:
PhD in the field of physics or physical chemistry or related field;
experience in laser spectroscopy or other optical methods of monitoring
molecular species; strong background in reaction dynamics, molecular beams,
spectroscopy or cold atom physics.
Desired:
Expertise in the monitoring of cold atoms and the trapping of cold atoms
with electric fields, magnetic fields or off-resonant laser traps.
Expertise in computer programming and data analysis is desired as well.
Sandia is an equal opportunity employer. This postdoctoral fellowship is
open to all nationalities. A resume including educational background,
relevant publications and the names of two professional references should
be sent to David W. Chandler, Senior Scientist, Div 8300, MS 9054, Sandia
National Laboratory, Livermore Ca.; Email [log in to unmask]
