Abstract:

Experimental limits on half-lives of the (0ν + 2ν)ββ decay of 130Te to excited states of 130Xe are obtained using low-background HPGe detectors. At the 90% CL, these limits are equal to 1.6 . 1021 y, 2.7 . 1021 y and 2.3 . 1021 y for transitions to the 2+1, 2+2 and 0+1 levels, respectively.
