Query: Polarized Structure Function $\sigma_{LT'}$ from $\pi^0 p$
  Electroproduction Data in the Resonance Region at $0.4$ GeV$^2 < Q^2 < 1.0$
  GeV$^2$   The first results on the $\sigma_{LT'}$ structure function in exclusive
$\pi^0p$ electroproduction at invariant masses of the final state of 1.5 GeV
$<$ $W$ $<$ 1.8 GeV and in the range of photon virtualities 0.4 GeV$^2 < Q^2 <
1.0$ GeV$^2$ were obtained from data on beam spin asymmetries and differential
cross sections measured with the CLAS detector at Jefferson Lab. The Legendre
moments determined from the $\sigma_{LT'}$ structure function have demonstrated
sensitivity to the contributions from the nucleon resonances in the second and
third resonance regions. These new data on the beam spin asymmetries in
$\pi^0p$ electroproduction extend the opportunities for the extraction of the
nucleon resonance electroexcitation amplitudes in the mass range above 1.6 GeV.
