新同位体$$^{241}$$Uを合成し、KISS施設の$$^{238}$$U+$$^{198}$$Pt系の多核子移行反応において、19種類の中性子過剰Pa-Pu同位体の系統的原子量測定が行われた。本実験結果は、この領域の核種において、$$N=152$$シェルギャップに向かう未踏の中性子過剰アクチニド同位体へのアクセスに多核子移行反応が重要な役割を果たすことを実証した。

The new isotope $$^{241}$$U was synthesized and systematic atomic mass measurements of nineteen neutron-rich Pa-Pu isotopes were performed in the multinucleon transfer reactions of the $$^{238}$$U+$$^{198}$$Pt system at the KISS facility. The present experimental results demonstrate the crucial role of the multinucleon transfer reactions for accessing unexplored neutron-rich actinide isotopes toward the $$N=152$$ shell gap in this region of nuclides.
