Change of nuclear configurations in the neutrinoless double-β decay of ¹³⁰Te → ¹³⁰Xe and ¹³⁶Xe → ¹³⁶Ba

NUCLEAR REACTIONS ^128,130Te, ^{130,132,134,136}Xe, ^136,138Ba(d, ³He), E=101 MeV; measured Ed, Id, σ(θ) using Grand Raiden (GR) spectrometer at RCNP-Osaka cyclotron facility. ^127,129Sb, ^{129,131,133,135}I, ^135,137Cs; deduced levels, L-transfers, spectroscopic factors. DWBA and optical model analysis. ^128,130Te, ^{130,132,134,136}Xe, ^136,138Ba; deduced ground state proton occupancies. Comparison with shell-model and interacting boson-model calculations.

RADIOACTIVITY ¹³⁰Te, ¹³⁶Xe(2β^-); deduced change in the configuration of valence protons between the initial and final states in the 0νββ decay mode from measurements of the cross sections in (d, ³He) reaction, nuclear matrix elements.
