Deformed Explicitly Correlated Gaussians
Matthew Beutel, Alexander Ahrens, Chenhang Huang +2
Deformed correlated Gaussian basis functions are introduced and their matrix elements are calculated. These basis functions can be used to solve problems with nonspherical potentia…
Adiabatic hyperspherical approach to large-scale nuclear dynamics
Yasuyuki Suzuki
We formulate a fully microscopic approach to large-scale nuclear dynamics using a hyperradius as a collective coordinate. An adiabatic potential is defined by taking account of all…
Electric dipole response of He: Halo-neutron and core excitations
D. Mikami, W. Horiuchi, Y. Suzuki
Electric dipole () response of He is studied with a fully microscopic six-body calculation. The wave functions for the ground and excited states are expressed as a superp…
Elastic and total reaction cross sections of oxygen isotopes in Glauber theory
B. Abu-Ibrahim, S. Iwasaki, W. Horiuchi +2
We systematically calculate the total reaction cross sections of oxygen isotopes, O, on a C target at high energies using the Glauber theory. The oxygen isotopes a…
Structure of and E2 transition in C in a C+n+n model
W. Horiuchi, Y. Suzuki
A three-body model of C+n+n is applied to study the energy spectrum and the hindered 2 transition in C. A realistic two-nucleon potential is used for the valence n…
Monte Carlo integration in Glauber model analysis of reactions of halo nuclei
Kalman Varga, Steven C. Pieper, Y. Suzuki +1
Reaction and elastic differential cross sections are calculated for light nuclei in the framework of the Glauber theory. The optical phase-shift function is evaluated by Monte Carl…
Ab initio approach to s-shell hypernuclei 3H_Lambda, 4H_Lambda, 4He_Lambda and 5He_Lambda with a Lambda N-Sigma N interaction
H. Nemura, Y. Akaishi, Y. Suzuki
Variational calculations for s-shell hypernuclei are performed by explicitly including degrees of freedom. Four sets of YN interactions (SC97d(S), SC97e(S), SC97f(S) and SC89(S…
G-Matrix Equation in the Resonating-Group Method
Yoshikazu Fujiwara, Michio Kohno, Choki Nakamoto +1
The G-matrix equation is most straightforwardly formulated in the resonating-group method if the quark-exchange kernel is directly used as the driving term for the infinite sum of…
Study of Light Lambda- and Lambda Lambda-Hypernuclei with the Stochastic Variational Method and Effective Lambda N Potentials
Hidekatsu Nemura, Yasuyuki Suzuki, Yoshikazu Fujiwara +1
We first determine the Lambda-N S-wave phase shifts so as to reproduce the experimental Lambda separation energies of A=3, 4 Lambda-hypernuclei, and then construct three phase-equi…
Lippmann-Schwinger Resonating-Group Formalism for NN and YN Interactions in an SU6 Quark Model
Yoshikazu Fujiwara, Michio Kohno, Tadashi Fujita +2
We formulate a Lippmann-Schwinger-type resonating-group equation to calculate invariant amplitudes of the quark-model baryon-baryon interaction. When applied to our recent SU6 quar…
Signature of the existence of the positronium molecule
J. Usukura, K. Varga, Y. Suzuki
The positronium molecule (Ps) has not been experimentally observed yet because its tiny (4.5 eV) binding energy cannot be detected when the molecule annihilates by emitting two…
New representation of orbital motion with arbitrary angular momenta
Y. Suzuki, J. Usukura, K. Varga
A new formulation is presented for a variational calculation of -body systems on a correlated Gaussian basis with arbitrary angular momenta. The rotational motion of the system…
