Background subtraction for Doppler-shift attenuation and angular correlation measurements with multi-detector Ge arrays

A novel background subtraction method for Doppler-shift attenuation and angular correlation measurements with large multi-detector HpGe arrays is presented. The formalism is designed for recently developed data base storage techniques with the event format resembling the original raw data structure. The background spectrum is constructed based on parameters extracted from one-dimensional spectra; the method, therefore, is complementary to currently applied methods which are designed for multi-dimensional, symmetrized histograms.
