The polarized longitudinal-transverse structure function ĻLTā²ā
has been measured in the Ī(1232) resonance region at Q2=0.40 and 0.65
GeV2. Data for the p(e,eā²p)Ļo reaction were taken at Jefferson Lab
with the CEBAF Large Acceptance Spectrometer (CLAS) using longitudinally
polarized electrons at an energy of 1.515 GeV. For the first time a complete
angular distribution was measured, permitting the separation of different
non-resonant amplitudes using a partial wave analysis. Comparison with previous
beam asymmetry measurements at MAMI indicate a deviation from the predicted
Q2 dependence of ĻLTā²ā using recent phenomenological
models.Comment: 5 pages, LaTex, 4 eps figures: to be published in PRC/Rapid
