| 内容記述 | The astrophysical origin of a rare isotope 115Sn has remained still an open question. An isomer (T1=2=14.1 y) in 113Cd is an s process branching point from which a nucleosynthesis flow reaches to 115Sn. The s process abundance of 115Sn depends on the isomer production ratio in the 112Cd(n, gamma)113Cd reaction. However, the ratio has not been measured in an energy region higher than the thermal energy. We have measured rays following neutron capture reactions on 112Cd in conjunction with a time-of-ight method at J-PARC. The relative gamma-ray intensity ratio of the isomer is almost constant in an energy region of up to 5 keV. This suggests that the s process contribution to the solar abundance of 115Sn is negligibly small. |
