通过重离子融合蒸发反应100Mo(11B,1p3n)106Pd布居了双偶核106Pd的高自旋态,选取的最佳入射束流能量为60MeV。实验在中国原子能科学研究院HI-13串列加速器上完成,采用Pb衬的100Mo靶,厚为1.56mg/cm2,Pb衬厚8.03mg/cm2,探测阵列由10套BGO-HPGe反康谱仪、2台HPGe小平面探测器和1个Clover探测器组成,通过在束γ谱学进行研究。实验总共积累了约2.3×108个两重以上的符合事件,利用133Ba和152Eu标准源对各个探测器进行了能量刻度和效率刻度。通
The best spin-beam energy of 60MeV was selected by the heavy ion fusion evaporation reaction of 100Mo (11B, 1p3n) 106Pd. Experiments were performed on a HI-13 tandem accelerator at China Institute of Atomic Energy using a Pb-lined 100Mo target with a thickness of 1.56mg / cm2 and a Pb liner thickness of 8.03mg / cm2. The detection array consisted of 10 BGO-HPGe anti-spectrum spectrometers , Two HPGe facets and a Clover detector, were studied by beam gamma spectroscopy. A total of about 2.3 × 108 double-coincidence events were accumulated in the experiment, and each detector was calibrated for energy and efficiency using 133Ba and 152Eu standard sources. through
