The experiment GAMMA performs nuclear structure studies in nuclei in the Z ~ 50 region using existing instrumentation like PRISMA and GASP at the National Laboratory of Legnaro.
The physics program includes the following topics:

• Mixed-symmetry states in the framework of the interacting boson model;

• Isospin symmetries and n-p pairing;

• Critical points and phase transitions between different nuclear shapes.

The GAMMA experiment also takes part to the development of new instrumentation for gamma-ray spectroscopy within the European collaboration AGATA.
