Yuri G. Zdesenko (Template:Lang-ua); 06 October 1943 – 01 September 2004, was a Ukrainian nuclear physicist known for a significant contribution to investigations of double beta decay.

Early life

Yuri G. Zdesenko was born on 06 October 1943 in Dmytrivka, Bakhmach Raion, Chernihiv Oblast, Ukrainian Soviet Socialist Republic of the Soviet Union to Soviet Army officer Georgy Zdesenko.

Academic career

In 1970 Yuri G. Zdesenko was graduated from Department of Physics of the T.G.Shevchenko Kiev State University. He obtained degrees of Candidate of Sciences (Philosophy Doctor) in 1981 (Institute for Nuclear Research, Moscow, Soviet Union), Doktor nauk in 1990 (Institute for Nuclear Research, Kyiv, Ukrainian Soviet Socialist Republic) and status of Full Professor in 2000 (Institute for Nuclear Research, Kyiv, Ukraine). Because of high scientific achievements, he was elected a Corresponding Member of the National Academy of Sciences of Ukraine in 2003.

Research

Yuri G. Zdesenko started researches in the Laboratory of Nuclear Physics of the T.G.Shevchenko Kiev State University (1970-1971) and in the Institute of Geochemistry and Physics of Minerals (1971-1980) where he dealt with neutron activation analysis of minerals and built up the low background set up for radiocarbon measurements. In the following he created the Laboratory for Low Background Measurements of the Special Construction Technological Center of the Institute for Nuclear Research of the Ukrainian Academy of Sciences (Kyiv, 1980-1986) where searches for of the double beta decay of 130Te[1], 96Zr[2]and 100Mo[3] were realized. The Laboratory was transformed in 1986 to the Lepton Physics Department of the Institute for Nuclear Research (Kyiv, Ukraine).

From 1983 the huge work has been fulfilled by Yuri G. Zdesenko and his group to build up the Solotvina Underground Laboratory in Solotvina, small town in the Zakarpattia Oblast on the west of Ukraine, in salt mines on the depth of 430 m underground. Starting from 1984, series of experiments were performed in this Laboratory devoted to search for rare α and β nuclear decays and for rare or forbidden in the Standard Model effects, mainly for neutrinoless double beta decay of atomic nuclei. The most valuable results obtained in the Solotvina Underground Laboratory are as following:

(1) the most stringent limits on neutrinoless double beta decay of 116Cd with cadmium tungstate crystal scintillators enriched in isotope 116Cd at 83% - in fact, one of the best world limits for this process[4][5][6];

(2) first observation of the two neutrino double beta decay of 116Cd[7][6];

(3) first observation of the alpha activity of tungsten (isotope 180W)[8];

(4) investigation of rare beta decay of 113Cd[9][10];

(5) search for neutrinoless double beta decay of 160Gd[11][12] and 186W[6].

Among others were searches for cluster nuclear decays, nuclear transitions to super-dense state, decays of nucleons into invisible channels, decays of electron with non-conservation of the electric charge, charge-non-conserving β decays. In many cases, investigations were fulfilled in collaboration with colleagues abroad. Yuri G. Zdesenko was author or coauthor of above 300 scientific publications for which there are near 1500 references in papers of other scientists.
