Our result indicates that the Λ-particle impurity effect causes the positive-parity ground state of 12ΛBe to revert to the normal state, i.e., negative parity. This parity reversion is attributed to the difference in the Λ binding energy between the positive- and negative-parity states, which in turn originates in the difference in α clustering and deformation.American Physical Society2015-01-16engjournal articleVoRhttp://hdl.handle.net/2115/58431https://doi.org/10.1103/PhysRevC.91.0143140556-28131089-490XPhysical Review C91114314https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/58431/1/PhysRevC_91_014314.pdfapplication/pdf558.55 KB2015-01-16
