Shape and structure of <sup>130</sup>Te relevant to 0νββ decay

ORAL

Abstract

The electromagnetic properties of low-lying states in a nucleus predicted to undergo neutrinoless double-beta decay - 130Te - has been studied using a high-precision multi-step Coulomb excitation experiment. The measurement was conducted at the ATLAS facility of the Argonne National Laboratory and the experimental setup consisted of the GRETINA multidetector array coupled to the charge heavy-ion counter, CHICO2. This configuration enabled precise Doppler correction and clean kinematic separation of the scattered particles. A comprehensive set of transition and static E2 matrix elements were extracted from the measured differential Coulomb cross sections and used to deduce the intrinsic shape parameters - overall deformation and asymmetry - using the model-independent rotational invariant sum rules. The resulting shape parameters will be discussed in the context of shape coexistence, with emphasis on the role of axial asymmetry in describing the structure of the 130Te nucleus.
