库仑激发多极化（耦合多极化）方法的第一次性能测试。它基于GSI Helmholtzzentrum für Schwerionenforschung（GSI）作为PreSPEC-AGATA活动的一部分进行的Aspin-flip实验。通过确定周围的预期excitations以及measuredexcitations的背景水平，上限的M1过渡强度的过渡和较低的光束的时间限制即将到来的实验活动利用耦合多极化已推断。使用AGATA在其预期的配置对这些估计的影响是通过Geant 4模拟推断。
A first performance test of the Coulomb excitation multipolarimetry (Coulex-multipolarimetry) method is presented. It is based on aspin-flip experiment performed as part of the PreSPEC-AGATA campaign at the GSI Helmholtzzentrum für Schwerionenforschung (GSI). Via determination of background levels around the expectedexcitations as well as measuredexcitations, an upper limit for theM1 transition strength of thetransition inand a lower beam time limit for upcoming experimental campaigns utilizingCoulex-multipolarimetryhave been inferred. The impact of the use of AGATA in its anticipatedconfiguration on these estimates is deduced viaGeant4simulations.
