通过对14.4 MeV/核子转移反应的三体耦合通道分析，确定了零能量的天体物理因子。采用连续离散耦合通道方法研究了破碎通道的影响。研究发现，分别在初始通道和最终通道中，通过和的破碎态的转移过程，特别是与基态的转移过程的干扰，使转移截面大大增加。对质子-中子相对坐标的有限范围效应约为20%。的结果，比先前的畸变波玻恩近似分析的结果小了约51%。
The astrophysical factor ofat zero energy,, is determined by a three-body coupled-channels analysis of the transfer reactionat 14.4 MeV/nucleon. Effects of the breakup channels ofandare investigated with the continuum-discretized coupled-channels method. It is found that, in the initial and final channels, respectively, the transfer process through the breakup states ofand, its interference with that through their ground states in particular, gives a large increase in the transfer cross section. The finite-range effects with respect to the proton-neutron relative coordinate are found to be about 20%. As a result of the present analysis,is obtained, which is smaller than the result of the previous distorted-wave Born approximation analysis by about 51%.
