The Few Body System Laboratory (FBSL) was formed in 1986. Scientific activity of the Laboratory is aimed at experimental study of structure of nuclei and nucleons using proton, deuteron, electron or positron beams. The scattered particles are detected in exclusive, semi-inclusive or inclusive kinematics. In most of experiments, polarization observables are measured.

The Laboratory combines investigations in the home Institute at PNPI synchrocyclotron with experiments being performed in cooperation with other research centres, both in Russia and abroad (see Historical overview
und Current projects).

The main activities of the FBSL at the present time (see Current projects) are listed below:

1. Study of nuclear medium effects in nuclei using quasi-free p,2p scattering at 1GeV;
   
   
2. Study of nucleon and hyperon spin structure in the HERMES experiment
   at the HERA electron (positron) beam (DESY, Hamburg). Presently, analysis of the experimental data;
   
   
3. Participation in OLYMPUS experiment at DORIS accelerator in DESY
   (years 2010-12);
   
   
4. Since the year 2003 the FBSL is involved in the PANDA project at GSI. Participation in the PANDA experiment is assumed to be the main activity of the Laboratory in the nearest future.
