Colloquim information

The planned colloquium is attached to JENAM-2000, so we supply in this

Information letter a short description on the meeting.

JENAM stays for "Joint European and National Astronomical Meting".

From May 29 through June 3, 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 astronomical 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.

Organizing CommitteeSCOPE 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.

The problems to be discussed are the following:

1. Excitation and ionization of atoms and molecules by electrons, protons

and heavier particles.

2. Dielectronic recombination and autoionization.

3. Banks and catalogues of atomic data in the Internet.

4. Codes for calculation of atomic and molecular parameters.

5. Use of atomic data in astrophysics: diagnostics of astrophysical plasma.

Main attention will be attracted to two directions of research.

1. 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.

2. Development of the methods of diagnostics of astrophysical plasma,

in particular of plasma with density and temperature fluctuations.

Construction of the methods of determination of differential emission

measure for the low density plasma.

It is also planned to discuss the possibility to organize a periodic

electronic journal "Atomic and molecular data for astrophysics".

In this journal the abstracts of the papers accepted for publication

in the fields of obtaining and using the atomic and molecular data

will be presented, together with the information how to get these

data. Scientific news will be also present: 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.

conference WEB pages. Participants who would like to make use of this

arrangement should fill in the corresponding part of the registration form

and submit it before March 15, 2000.

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 receive 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 put at the

WEB page of the meeting and may be found at
