Description
Summary:	In this article, we present current results of the experiment searching for double beta decay of <sup>106</sup>Cd with the help of an enriched <sup>106</sup>CdWO<sub>4</sub> crystal scintillator in coincidence with two CdWO<sub>4</sub> scintillation detectors. The experiment is carried out at the Gran Sasso underground laboratory of the National Institute for Nuclear Physics (LNGS INFN, Italy). After 1075 days of data-taking, no double-beta effects were observed. New half-life limits have been set for the different modes and channels of double beta processes in <sup>106</sup>Cd at the level of <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mo movablelimits="true" form="prefix">lim</mo><msub><mi>T</mi><mrow><mn>1</mn><mo>/</mo><mn>2</mn></mrow></msub><mo>=</mo><msup><mn>10</mn><mn>20</mn></msup><mo>−</mo><msup><mn>10</mn><mn>22</mn></msup></mrow></semantics></math></inline-formula> years.
