New limits on the ${\beta\beta}$ decay of 
${^{130}Te}$ to excited states of ${^{130}Xe}$

Abstract

Experimental limits on half-lives of the

(0\nu + 2\nu)\beta\beta

decay of

^{130}

Te to excited states of

^{130}

Xe are obtained using low-background HPGe detectors. At the 90% CL, these limits are equal to

1.6\cdot 10^{21}

y,

2.7\cdot 10^{21}

y and

2.3\cdot 10^{21}

y for transitions to the

2^+_1

,

2^+_2

and

0^+_1

levels, respectively
