Abstract

A first performance test of the Coulomb excitation multipolarimetry (Coulex-multipolarimetry) method is presented. It is based on a ⁸⁵Br πp_3/2 → πp_1/2 spin-flip experiment performed as part of the PreSPEC-AGATA campaign at the GSI Helmholtzzentrum für Schwerionenforschung (GSI). Via determination of background levels around the expected ⁸⁵Br excitations as well as measured ¹⁹⁷Au excitations, an upper limit for the M1 transition strength of the 1/2^-→ 3/2^- g.s. transition in ⁸⁵Br and a lower beam time limit for upcoming experimental campaigns utilizing Coulex-multipolarimetry have been inferred. The impact of the use of AGATA in its anticipated 1π configuration on these estimates is deduced via Geant4 simulations.
