Announcement and Call for Papers: COSPAR Session on Gamma-Ray Spectroscopy


The 35th COSPAR Scientific Assembly will be held in  in Paris, France, over
the period 18-25 July, 2004. As part of this, there will be a Session

E1.5: "INTEGRAL: New Perspectives for Astrophysical Nucleospectroscopy".

This Session is intended to highlight the science which is addressed by the
ESA INTEGRAL Observatory with the SPI Spectrometer as one of the main
telescopes aboard the satellite. This provides excellent spectroscopy power
in the domain of nuclear lines, thus allows the study of radioactivities
from nucleosynthesis events such as novae and supernovae, nuclear
excitations by energetic interactions from cosmic rays or near accreting
compact objects, and positron annihilation in interstellar space or plasma
jets from black holes.

The contributions in this Session are intended to first demonstrate the
capabilities of the INTEGRAL instruments for nucleospectroscopy in view of
detector performances and instrumental backgrounds, and broadly discuss the
science which can be or is made with gamma-ray line measurements from
supernovae and supernova remnants, from novae, from black-hole candidates
and accreting neutron stars, and from prominent regions of interstellar
matter such as the Galactic Center region.
Overlap of astrophysical issues with other Sessions of the Assembly may be
specifically with:
   E1.4 "Young Neutron Stars and Supernova Remnants"
   E1.6 "Sources of Cosmic Rays in the Galaxy"
These have been coordinated to not conflict in schedule with  the INTEGRAL
Session.


We herewith invite your contributions to the discussions of this Session.
There will be oral and poster contributions.
There are two invited talks to set the stage for this Session:
     Jordi Isern: INTEGRAL Perspectives for Supernova and Nova Science So,
if you work on or intend to address these issues, and consider gamma-ray
spectroscopy as one of the observational constraints, your contribution is
welcome in Session E1.5
