| 英文摘要 | The experimental B(GT) strengths of the Fe-59 excited states were employed to determine the transition strengths which greatly contribute Fe-59 stellar beta-decay at typical carbon shell burning temperature. The result has been compared with the theoretical rates FFN (Fuller-Fowler-Newman) and LMP (Langanke&Martinez-Pinedo). Impact of the newly determined rate on the synthesis of cosmic gamma-emitter 60Fe has also been studied using one-zone model calculation. Our results show Fe-59 stellar beta-decay rate plays an important role in the Fe-60 nucleosynthesis. However the uncertainty of the decay rate is rather large due to the error of B(GT) strength that requires further studies. |
