被引用回数:1 パーセンタイル:0.02(Physics, Nuclear)A -decay unstable isomer with a half-life of 14.1 y at 264 keV in Cd is a branching point in the process, from which a weak branch reaches to a rare tin isotope Sn whose astrophysical origin has been an open problem. We have measured rays decaying to the ground state or the isomer in the Cd()Cd reaction using high-energy resolution detectors in conjunction with a time-of-flight method. The relative production ratios of the isomer to the total following the neutron capture reactions on Cd have been evaluated in an energy region of up to 9 keV, and the spin and parity of several resonances have been assigned.
