Neutrinoless double beta decay with Xe-136 in BOREXINO and the BOREXINO Counting Test Facility

This article discusses the methods and sensitivity for a double beta decay experiment based on the Xe-136 candidate for BOREXINO or the BOREXINO Counting Test Facility. Different background assumptions and experimental configurations are studied, assuming a data obtaining period of one year. The related experimental problems are discussed, and summary tables containing the sensitivity estimates for the various configurations are presented. (C) 2000 Elsevier Science B.V.
