“…On the contrary, the calculated B(E2) = 15, 18, 17, 17e 2 fm 4 (A = 18 − 24) stays almost constant. The calculation underestimates the experimental B(E2) value [43,44,32,45] by a factor of 3-1.5 for 18,20 O, but with reasonable agreement in 22 O. The calculated B(E2) values differs by a factor of 0.5-1.5 from the quasiparticle RPA calculation in Ref.…”

“…The present theory includes all the three groups as seen in Eq. (43), whereas the previous approaches include only the configurations where only one nucleon is in the continuum states. Escaping processes of one particle to the external region takes part in at the excitation energyhω > E th,1 above the one-particle threshold, and consequently the strength functions show continuum spectra.…”

Continuum linear response in coordinate space Hartree–Fock–Bogoliubov formalism for collective excitations in drip-line nuclei

2001

View full text Add to dashboard Cite

We formulate a continuum linear response theory on the basis of the Hartree-FockBogoliubov formalism in the coordinate space representation in order to describe low-lying and high-lying collective excitations which couple to one-particle and two-particle continuum states. Numerical analysis is done for the neutron drip-line nucleus 24 O. A low-lying collective mode that emerges above the continuum threshold with large neutron strength is analyzed. The collective state is sensitive to the density-dependence of the pairing. The present theory satisfies accurately the energy weighted sum rule. This is guaranteed by treating the pairing selfconsistently both in the static HFB and in the dynamical linear response equation.

Dynamical core deformation effects on single-nucleon knockout reactions at fragmentation beam energies

2005

View full text Add to dashboard Cite

The effects of core deformation and of its dynamical reorientation and rotational excitation on the inclusive single-neutron knockout reaction cross sections on light spherical target nuclei are examined. The projectile nuclei are modeled within the framework of a weak-coupling, quadrupole-deformed core-plus-neutron two-body model. We formulate the inclusion of this non-spectator-core degree of freedom within the nonperturbative eikonal model and calculate the elastic and inelastic breakup (or stripping) neutron-removal cross sections. We apply the methods to model the single-neutron removal reactions induced by 11 Be and 17 C secondary fragmentation beams incident on a 9 Be target. Our calculations indicate that dynamical deformation effects on the elastic breakup component of the knockout cross section can be significant. This is the largest effect. The more geometrical stripping cross section is found to be hardly changed by the inclusion of the deformed core degree of freedom.

“…This almost constant trend of the g-factor data is not, however, observed in either the energies of the 2 + 1 states [11][12][13][14][15] (Fig. 1(b)), which show a steady decrease with N , or in the B(E2:0 + 1 → 2 + 1 ) values [12,[15][16][17] (Fig. 1(c)), which increase with increasing N .…”

The transient field perturbed angular correlation technique has been used with Coulomb excitation in inverse kinematics to perform a systematic measurement of the g factors of the first excited 2 + 1 states in the stable even-A isotopes 96−104 Ru. The measurements have been made relative to one another under matched kinematic conditions and include the first measurement of the g(2 + 1 ) = +0.47(3) in 96 Ru.
