Dear spectroscopists,
Below is the abstract of the talk I am planning to give at the PANic11 at
MIT in July this year.

Exclusive $\pi^{0}$ electroproduction in the resonance region at low $Q^{2}$.

 We report the analysis of single $\pi^{0}$ electroproduction in the
resonance region to study the electromagnetic excitation of the nucleon
resonances. The study is aimed at understanding of the internal structure
and dynamics of the nucleon. The experiment was performed using an
unpolarized cryogenic hydrogen target and 2.0 GeV polarized electron beam
during the e1e run period with CLAS detector at Jefferson Lab.
 The new measurements will produce a data base with high statistics and
broad kinematic coverage for the hadronic invariant mass W up to 1.8 GeV
in the momentum transfer $Q^{2}$ range of 0.4 - 1.0 (GeV/c)$^{2}$ with
the full angular coverage.
Preliminary results will be presented and compared with the various model
calculations.

All the comments and suggestions will be appreciated.
Best regards, Nick.
