Nuclear Structure
• Importance – Exotic nuclei far from the valley of beta stability
– Nuclear astrophysics
• Development of many-body techniques for the nuclear shell model
• Close collaboration with several experiments:– CERN (Isolde), GSI (Germany), Lund (Sweden), NBI (Denmark),
Surrey (UK), etc.
• Studies of the thermodinamical properties of finite nuclei, collaboration with Oslo cyclotron laboratory
• Properties of dense matter

Freeze-out
• Describes the final stages of heavy-ion collisions:– all interaction cease in the systems
• Different theoretical models have been hired:– Kinetic models
– Field theoretical approach
Subatomic theory progress report
Bergen, September 2002
Freeze-out: kinetic approach
• Express macroscopic measurables using the microscopic properties of the system
• Important issues:» Timelike, spacelike freeze-out surfaces
» Conservation laws
» Coooper-Frye formula
• Our models:» cut Juttner distribution
» idealized model with drain term
» freeze-out distribution with rescattering
» four volume emission model
