CONNECTED COLLOQUIUM No. 3

Atomic and Molecular Data For astrophysics

Organizing Committee

The planned colloquium is a part of JENAM-2000 , so in this Information letter, a short description of this meeting is given.

JENAM stays for " Joint European and National Astronomical Meeting .

From May 29 through June 9, 2000 Moscow will host the 9th Meeting of European Astronomical Society (EAS) jointly with the 5th General Assembly of Euro-Asian Astronomical Society (EAAS). The Meeting is open for all astronomers. Its scientific program covers the basic fields of astronomy and astrophysics.

During the Conference, both the fundamental astronomy knowledge and the exciting new results in experimental and theoretical astrophysics will be presented by experts in the field. We anticipate that the Conference will provide new prospects for current research and a first class opportunity to European astronomers to strengthen their bonds.

SCOPE OF THE COLLOQUIUM

Presently, astrophysics is one of the most important fields of application of spectroscopic data. It is planned to use the opportunity presented by the colloquium for discussions on the modern methods of obtaining experimentally and theoretically of a vast bulk of atomic and molecular data for various astrophysical problems and the ways how to use them.

Here are the problems to be discussed:

• Excitation and ionization of atoms and molecules by electrons, protons and heavier particles.
• Dielectronic recombination and autoionization
• Codes for calculation of atomic and molecular parameters.
• Banks and catalogues of atomic data in the
• Use of atomic data in astrophysics: diagnostics of astrophysical plasma.

A special session will be organized to discuss two important directions of research.

• Comparison of different approximations in calculation of the cross sections for excitation and ionization of atoms, molecules and their ions by electrons and protons for wide energy intervals, and for numerous sets of the target states, including transitions between highly excited states, and ionization cross sections from these states, aimed at choosing most adequate approximations for the problem under consideration.
• Comparative merits and drawbacks of such approaches as Born and Born-Coulomb approximations, Distorted Wave approximations, Close Coupling and R-matrix approximations and semiclassical approaches will be considered.
• Development of the methods of diagnostics of astrophysical plasma, in particular, of plasma with density and temperature fluctuations. Development of methods for differential emission measure determination for the low density plasma.

It is also planned to discuss the organization of a periodic electronic journal "Atomic and molecular data for astrophysics". In this journal the Abstracts of papers accepted for publication in the field of obtaining and using the atomic and molecular data will be presented, together with the information on the way to access these data. Scientific news will be also presented: New catalogues and Atomic data banks or their Essential modifications, Conferences and Meetings in the fields of the atomic and molecular spectroscopy, new Methods and Programs, ect.

FINANCIAL SUPPORT

A limited number of participants (mainly, the young ones) will receive financial support to attend the JENAM-2000 meeting upon the decision of scientific sections' conveners and LOC. A filling in the Registration form for the main JENAM-2000 meeting is mandatory for receiving the support. To apply for the financial support, please indicate it in the registration form before March 15, 2000.

If you plan to participate in the Colloquium only and need a support for your travel and living expenses, please, contact with A.F.Kholtygin (see e-mail address at the end of the document). The SOC plan to get financial aid specially to facilitate the attending Colloquium for participants from Russia and NIS.

POSTER SESSION AND INTERNET PARTICIPATION

The contributions to the colloquium can be presented in 5th forms: Invited Lecture (40 m), Oral (20 m), Short Oral (10 m), Poster and Internet Presentation. The last is the full text of the report from those of the potential participants who will be unable to arrive to the meeting in the planned dates. The reports of those participants will be presented at the WEB page of the meeting and may be found at
