In the frame of the european project SCANS (Software for Computer Aided Neutron Scattering) a post-doc position is open at the OGG-INFM in Grenoble. Its function will be the development of Monte Carlo kernels describing the transport properties of neutron/x-ray optical elements, in particular for polarized neutrons, time of flight instrumentation and the scattering from generic samples. The codes will then be tested by performing "ad hoc" experiments either at the ILL or ESRF. The work will be carried out in the frame of the existing collaboration among INFM, ILL and ESRF.
The successful candidate should hold a doctorate in Physics, Chemical Physics, Chemistry or similar fields or have at least three years of research experience and should have a good general knowledge in Physics and possibly in x-ray or neutron scattering. He/she should also have good computer and experimental skills.
The duration of the contract is initially for 1 year with a very high possibility of extension depending on the results obtained.
The deadline is 17/6/2000.

The position is tenable for 3 years.
Research on the dynamical structure of soft matter and biological macromolecules
This position is open to post-doctoral candidates who are looking for an entry position in research. The research activities of the successful candidate will be centered around studies of the static and dynamical structure of soft matter (e.g. hydrated anorganic and organic multilayers, such as layered ionic conductors, clays, phospholipid-surfactant system; micelles, polymers, solutions, etc.) and of biological macromolecules (e.g. membranes, proteins, enzymes, ion pumps, etc.). Research methods comprise neutron scattering techniques, especially wide-angle and small-angle time-of-flight spectroscopy and include extensive computer model calculations. Various complementary sample characterization techniques (e.g. DSC and broadband dielectric spectroscopy) are available. The successful candidate will also participate in experiments of user groups, who carry out research with the time-of-flight spectrometer NEAT in many different areas of condensed matter research.
A broad knowledge in the field of condensed matter, either in physics, physical chemistry, biophysics or biochemistry is a prerequisite. Experience with at least one of the spectroscopic techniques (neutron scattering, IR, Raman, light scattering, diel. spectroscopy...) or in small angle scattering is desirable. Experience with computer aided modelling and the programming of models would be advantageous.
For further details about the post contact Dr. R.E. Lechner (+49(30)8062-2780, e-mail: [email protected].
Applicants should send a letter of application, CV, names and addresses of
two references, and a list of publications to
Dr. R.E. Lechner, Hahn-Meitner-Institut, Abt. SF1, Glienicker Str. 100, D-14109 Berlin)
before 23 June 2000.
I would like to hear from someone wishing to do a PhD in neutron scattering from protons or deuterons in metals. The student would participate in the ab initio calculations of the excited wave functions and the measurement of the corresponding inelastic cross sections. Standard ab initio calculations have to be modified to allow for the effect of the proton zero point energy. Comparisons with experiment for PdH are excellent (See PLR 84 (2000) 1531). However, it now seems likely that the traditional explanations have to be modified to take account of Franck-Condon levels, where the final state is the trapped excited state. The experimental side will involve use of facilities at the ILL, Grenoble and ISIS (Rutherford Appleton Laboratory) and the student could be based at the Rutherford Appleton Laboratory or in Manchester.
Anyone interested, please contact me by email ([email protected]).
The support would be at the normal level for a post graduate
student in the UK,
with funding method depending a bit on nationality.

A full-time postdoctoral research associate position in protein crystallography is presently available. The research entails crystallographic analysis of the structure and mechanism of mitochondrial transhydrogenase, an integral membrane protein and model system for the study of proton translocation. Diffraction quality crystals of the soluble NAD(H) binding domain are in hand, and a high-resolution structure of the soluble NADP(H) binding domain has been solved. The research includes structure determination of the 80 kD NAD(H) binding domain, and of the reduced NADH and NADPH bound forms of both soluble domains. Further, the opportunity exists to crystallize the holoenzyme comprised of the interacting soluble domains and the integral membrane proton channel domain. The project is in collaboration with Youssef Hatefi in the Dept. of Molecular and Experimental Medicine at Scripps where mutagenesis and biochemical experiments are being done in parallel with the structural analysis. Scripps provides an exciting environment for structural biology with a large number of investigators active in crystallography of biological macromolecules. Outstanding resources and facilities are available, including access to the new Scripps-Stanford beam line (BL 11-1) at SSRL.

An Indiana University postdoctoral position is available in the Indiana/NIST program for the development and application of polarized 3He-based neutron spin filters to materials science and fundamental physics. In the development area, we are pursuing both metastability-exchange optical pumping (Indiana and NIST) and spin-exchange (NIST) to produce the polarized 3He gas. Current applications in materials science include small angle neutron scattering at NIST and polarized neutron reflectomtery at the Intense Pulsed Neutron Source at Argonne National Lab. 3He-based spin filters can also be used in experiments involving the weak interaction of neutrons, and experiments in various stages of preparation intend to use this technology.
The candidate will be based at the Indiana University Cyclotron Facility in Bloomington, Indiana, with trips to the NIST Center for Neutron Research in Gaithersburg, Maryland and/or the Argonne Intense Pulsed Neutron Source near Chicago.
This work is quite interdiscliplinary, so applicants from the fields of AMO physics, nuclear physics, or neutron scattering will be considered. Applicants should have a Ph.D. in physics. The position is available immediately, but any starting date before Dec. 2000 can be accomodated.
