• 論文の詳細を見る

• A new short-lived isomer in ^<114>Sb was found by using the technique of the in-beam gamma spectroscopy. Two new gamma rays at energies of 96 keV and 326 keV, decaying with a half-life of 275±20 μsec, were found. A ratio of the intensities of the 326 keV gamma ray to that of the 96 keV gamma ray was obtained to be 1.0:0.34. The character of the 326 keV gamma ray was deduced to be an E3 transition and was found to be enhanced 6.9 times than the single particle estimate. The 96 keV transition was concluded to be an E2 transition. A decay sequence of 8^--326 keV (E3)⟶5^+-96 keV (E2)⟶3^+ (ground state of ^<114>Sb) may be proposed. The observed enhancement of the E3 transition is explained in terms of a mixture of the E3 core polarization.
