Lifetime measurements in Mo 102 interpreted in the interacting boson model and the X(5) symmetry

Lifetimes of low-lying excited states in Mo102 populated in the two-neutron transfer reaction Mo100(O18,O16)Mo102 were measured using the recoil distance Doppler shift method at the IFIN-HH Tandem accelerator. Lifetimes of the 21+, 02+, 41+, 22+, 23+, 31+, 61+, (03+), 42+, (31-), and (51-) states were obtained. The deduced electromagnetic transition strengths have been compared to calculations performed in the interacting boson model framework including models representing the U(5) and X(5) symmetries. It is found that Mo102 lies between the U(5) limit and the X(5) critical point symmetry. © 2025 authors. Published by the American Physical Society.

International audienceLifetimes of low-lying excited states in Mo102 populated in the two-neutron transfer reaction Mo100(O18,O16)Mo102 were measured using the recoil distance Doppler shift method at the IFIN-HH Tandem accelerator. Lifetimes of the 21+, 02+, 41+, 22+, 23+, 31+, 61+, (03+), 42+, (31−), and (51−) states were obtained.
