Measurements of Octupole Collectivity in \ (^90, 91 Zr\)

Key Points

To measure octupole collectivity in the 90Zr and 91Zr isotopes through excitation experiments.
Conducted Coulomb excitation with an 88 MeV 32S beam on 90Zr.
Utilized particle–gamma coincidence detection.
Performed a separate measurement using 82Se(13C, 4n) reaction for 91Zr.
Employed electronic fast timing method to determine the lifetime of the states.
Populated the 3^-1 state in 90Zr at 2748 keV.
Determined the electromagnetic matrix element for 90Zr.
Measured significantly high B(E3) strength for the 11/2^-1 state in 91Zr.

Abstract

A Coulomb excitation experiment has been performed with the aim of populating the \ (3^-₁\) state in \ (^90 Zr\) at 2748 keV excitation energy with 88 MeV \ (^32 S\) beam and particle–\ (\) coincidence mode. A preliminary analysis has been performed to determine the electromagnetic matrix element. In a separate measurement, the octupole collective \ (11/2^-₁\) state in \ (^91 Zr\) has been populated by the \ (^82 Se (^13 C, 4n) \) reaction. Significantly high \ (B\) (E3) strength has been determined by measuring the lifetime of this state through the electronic fast timing method.
