We measured absolute cross sections for neutron transfer channels populated in the ${}^{94}\mathrm{Rb}+{}^{208}\mathrm{Pb}$ binary reaction. Cross sections have been extracted identifying directly the lead isotopes with the high efficiency MINIBALL $\gamma$-ray array coupled to a particle detector combined with a radioactive ${}^{94}\mathrm{Rb}$ beam delivered at $E_{\mathrm{lab}}=6.2$ MeV/nucleon by the HIE-ISOLDE facility. We observed sizable cross sections in the neutron-rich mass region, where the heavy partner acquires neutrons. A fair agreement between the measured cross sections with those from GRAZING calculations gives confidence in the cross-section predictions of more neutron-rich nuclei produced via a larger number of transferred nucleons.

使用abb94放射性束的二元反应中铅同位素的种群

我们测量了中子传输通道的绝对横截面 ${}^{94}b+{}^{208}\mathrm{铅含量}$二元反应。提取了横截面，可直接识别具有高效率MINIBALL的铅同位素$\gamma$射线阵列耦合到结合了放射性的粒子探测器 ${}^{94}b$ 光束在 ${Ë}_{\mathrm{实验室}}=6.2$MeV /核子由HIE-ISOLDE设备提供。我们在富含中子的质量区域观察到了相当大的横截面，在那里重的伙伴获得了中子。测量的横截面与GRAZING计算的横截面之间的合理协议，使人们对通过大量转移的核子产生的更多中子富核的横截面预测充满信心。
