New measurement of double-β decays of ¹⁰⁰Mo to excited states of ¹⁰⁰Ru with the CUPID-Mo experiment

RADIOACTIVITY ¹⁰⁰Mo(2β^-); measured Eβ, Iβ, Eγ, Iγ, βγ-coin; deduced particles multiplicities, matrix elements T_1/2 for 2νββ-decay to first excited 0⁺ state in ¹⁰⁰Ru, T_1/2 limits for 0νββ-decay to first excited 2⁺ and first 0⁺ states in ¹⁰⁰Ru, T_1/2 limits for 2νββ-decay to first excited 2⁺ state in ¹⁰⁰Ru, limits on Majorana neutrino mass. Bolometric technique. CUPID-Mo setup - array of 20 Li₂¹⁰⁰MoO₄ (LMO) calorimeters, each equipped with a Ge-wafers light detector.
