We perform coupled-cluster calculations of ground-and dipole excited-state properties of the He 8 halo nucleus with nucleon-nucleon and three-nucleon interactions from chiral effective …

Background: The four-neutron correlation has been attracting much attention for decades. In addition to the study on the tetraneutron system, it is worthwhile to investigate the correlation …
The relativistic mean-field model, augmented with three types of center-of-mass corrections and two types of rotational corrections, is employed to investigate the ground-state …
Bulk properties, spectrum, and nuclear response of He 8 are investigated within the equation of motion phonon method, which generates an orthonormal basis of n-phonon …
In this work, we present new ab initio coupled-cluster calculations of dipole-excited state properties of 8 He based on the chiral effective field theory interaction 1.8/2.0 (EM). We focus …

In neutron-rich 8He, we study the soft dipole resonance, which is regarded as a dipole oscillation of four valence neutrons against the 4He core, and its effect on the low-energy …
With an extreme neutron-to-proton ratio of N/Z= 3, He 8 provides an ideal laboratory for the study of a variety of exotic phenomena, such as the emergence of a soft dipole mode that is …
We investigate the soft dipole resonance in the proton-rich nucleus C 2 6 8, which is a collective dipole oscillation of four valence protons against the α core, and discuss the …

Background: The no-core shell model (NCSM) is an ab initio method that solves the nuclear many-body problem by expanding the many-particle wave function into a (typically) …
