An appratus with a compact ECR ion source and a electrostatistic product-ion
analyzer has been developed to study photoabsorption processes of ions
(including multiply charged ions) at the SPring-8. The priliminary results
of the characteristics of the apparatus is reported. Outline of future
experiments is briefly described.
