Search for double-β decay processes in ¹⁰⁶Cd with the help of a ¹⁰⁶CdWO₄ crystal scintillator

RADIOACTIVITY ¹⁰⁶Cd(2β⁺), (2EC), (β⁺EC); measured Eγ, Iγ, Eα, Eβ, radioactivity trace contamination in ¹⁰⁶CdWO₄ scintillator, enriched cadmium; deduced half-life limits for neutrinoless and two-neutrino 2β⁺, 2EC, and β⁺EC decays to excited states in ¹⁰⁶Pd. Low-background experiment at Gran Sasso underground laboratory. Comparison with QRPA calculations for resonant neutrinoless double electron capture. ^212,216Po, ²²⁰Rn(α); measured half-life.
