| Popis: | Data from scattering polarized electrons, linearly accelerated up to 850 MeV energy, off polarized hydrogen and deuterium targets have been collected with BLAST Spectrometer at Bates Laboratory of Massachusetts Institute of Technology (MIT) between 2003 and 2005. Among these data, the analysis of the electron-deuteron scattering part of the data for the measurement of the double spin asymmetry via pion photo-electro production technique has begun recently. Here, we present four momentum transfer square (Q2) and the invariant mass (W) spectra, and its dependence to Q2 as the initial results of the analysis. It was seen that the results satisfied the theoretical expectations. In addition, due to the necessity that the later analysis will be done in the resonance region, it was understood that the condition of W of the scattering being above 1.1 GeV/c2 has to be met for the isolation of the region from the non resonant one. |
