Vibrational Modes in Strongly Deformed Nuclei
Y. Tsunoda, T. Otsuka, N. Shimizu +3
Low-energy vibrational excitations associated with the fluctuation of quadrupole deformed shapes are discussed within the frame of state-of-the-art Configuration Interaction calcul…
Underlying structure of collective bands and self-organization in quantum systems
Takaharu Otsuka, Yusuke Tsunoda, Takashi Abe +2
The underlying structure of low-lying collective bands of atomic nuclei is discussed from a novel perspective on the interplay between single-particle and collective degrees of fre…
Ground-state properties of doubly magic nuclei from the unitary-model-operator approach with the chiral two- and three-nucleon forces
T. Miyagi, T. Abe, M. Kohno +5
The ground-state energies and radii for He, O, and Ca are calculated with the unitary-model-operator approach (UMOA). In the present study, we employ the simila…
Introduction of the one-body correlation operator in the unitary-model-operator approach
Takayuki Miyagi, Takashi Abe, Ryoji Okamoto +1
In the earlier unitary-model-operator approach (UMOA), one-body correlations have been taken into account approximately by the diagonalization of unitary-transformed Hamiltonians i…
Large-scale shell-model analysis of the neutrinoless decay of Ca
Y. Iwata, N. Shimizu, T. Otsuka +4
We present the nuclear matrix element for the neutrinoless double-beta decay of Ca based on large-scale shell-model calculations including two harmonic oscillator shells ($s…
Ground-state energies and charge radii of He, O, Ca, and Ni in the unitary-model-operator approach
Takayuki Miyagi, Takashi Abe, Ryoji Okamoto +1
We study the nuclear ground-state properties by using the unitary-model-operator approach (UMOA). Recently, the particle-basis formalism has been introduced in the UMOA and enables…
