重イオン深部非弾性散乱により中性子数20近傍の中性子過剰核を合成し、ナノ秒の寿命を持つ核異性体を探索した。$$gamma$$線の角度分布と寿命測定から$$^{32,33}$$Si, $$^{34}$$Pの核異性体のスピン・パリティを明らかにし、中性子が$$f_{7/2}$$軌道へ励起した状態であることを明らかにした。

Nanosecond isomers in neutron-rich N$$sim$$20 nuclei produced in the heavy-ion deep-inelastic collision have been searched for. Spin-parities of the isomers in $$^{32,33}$$Si and $$^{34}$$P have been identified through $$gamma$$-ray angular distribution and lifetime measurements. It has been found that these isomers arise from the neutron excitation on the $$f_{7/2}$$ orbitals.
