用EUROGAM 2系列反康普顿谱仪和IGISOL质量分离器分别对~（248）Cm自发裂变和~（238）U质子诱发裂变产生的~（113）Ru和~（113）Rh核进行了瞬发γ谱研究。对于我们最近在113 Ru中发现的0.5s异构体，我们提出了7/2-[523]构型。目前的数据表明自旋和宇称1/2+的基态在113 Ru。这一结果和113 Rh激发态的一些新数据有助于重新解释和更好地理解113 Ru的β-{}衰变图。在核-准粒子耦合模型的框架下研究了~（113）Ru的性质，较好地再现了实验数据。
The113Ru and113Rh nuclei, produced in the spontaneous fission of248Cm and in proton-induced fission of238U , were studied by means of prompt gamma spectroscopy using the EUROGAM 2 array of Anti-Compton spectrometers and the IGISOL mass separator, respectively. For the 0.5s isomer, found in113Ru in our recent study we propose the 7/2-[523] configuration. The present data indicate spin and parity 1/2+for the ground state in113Ru . This and some new data on the excited levels in113Rh allows reinterpretation and a better understanding of the β-{}decay scheme of113Ru . The properties of113Ru were studied in the frame of the Core-Quasiparticle Coupling model, which has well reproduced the experimental data.
