【摘要】 实验测量了25 MeV/u的6He+9Be反应中的单、双中子转移微分截面.利用反应耦合道模型初步分析了实验数据,计算大体重现截面值.转移反应对末态有相当的选择性,并且双中子转移截面主要来自到基态的一步过程.后角度截面的上升可能与连续态的耦合有关.
【Abstract】 Differential cross sections for quasi-elastic scattering at forward angles and for In and 2n transfer reaction at backward angles induced by 6He at 25 MeV/u from 9Be target were measured. The experimental data were analyzed in the framework of the CRC model. The raise at backward angle of the 1n and 2n transfer cross section can not reproduced by the current calculation.
