In order to probe the 2v-mode of the double beta-decay of [sup 136]Xe, decay daughters ([sup 136]Ba) 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 [sup 136]Ba 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.
