NOVA PhD or Postdoc-Position
=============================
Raymond and Beverly Sackler Laboratory for Astrophysics
========================================================
Leiden Observatory, University of Leiden, the Netherlands
Deadline: September 15, 1999
A 4-yr PhD or 2-yr postdoc position is available starting this fall at the
Raymond and Beverly Sackler Laboratory for Astrophysics (SLA) of the Leiden
Observatory. The research concerns the simulation of the chemical processes
that take place on the surfaces of dust grains in star-forming regions in
interstellar space. This research will make use of a new experimental set-up
in which an intense beam of atomic gas (H, O, N) is produced and aimed at an
ice sample (CO, O2, N2) that has been deposited on a cold substrate (~12 K).
The reaction products will be analyzed by infrared spectroscopy and mass
spectroscopy. The objective of the experiments is to obtain insight into the
basic processes responsible for the formation of molecules such as H2O, CH3OH,
CO2, NH3 and HCOOH observed in icy mantles in space, and will lead to a better
understanding of the chemical processes associated with star formation. The
research will be directed by Dr. W.A. Schutte and Prof. E.F. van Dishoeck, and
is in collaboration with Dr. P. Ehrenfreund, Prof. A.G.G.M. Tielens (SRON/RuG)
and others. See http://www.strw.leidenuniv.nl/~lab for further information.
Applications should include a curriculum vitae (with a list of publications
and grades for exams), a brief statement of research experience, and the names
of two people who can serve as a reference. De deadline for the application is
SEPTEMBER 15 1999. The position is open to students of all nationalities with
the equivalent of a "doctoraal" (Masters) degree. The starting date for the
position is flexible. Astronomy, physics and chemistry students are all
encouraged to apply. Some experience with experimental work, in particular in
the fields of ultra-high vacuum techniques, mass spectroscopy or infrared
spectroscopy is desirable, but not a prerequisite. Please send all information
and questions to:
