摘要：

In order to probe the 2v-mode of the double beta-decay of Xe-136, decay daughters (Ba-136) were accumulated under an electric field on the surface of a spherical electrode in a positive ion collector filled with liquid xenon, and were then observed with a time-of-flight mass spectrometer. The positive ion collector was operated for 847 hours using natural liquid xenon of 3 liters. No Ba-136 isotopes were detected with the time-of-flight mass spectrometer. However, it was found that a collector electrode made of stainless steel was free from contamination of natural barium isotopes as background.
