Giant resonances inU238within the quasiparticle random-phase approximation with the Gogny force

Abstract: Fully consistent axially-symmetric deformed quasiparticle random-phase approximation (QRPA) calculations have been performed, using the same Gogny D1S effective force for both the Hartree-Fock-Bogolyubov mean field and QRPA matrix. New implementation of this approach leads to the applicability of QRPA to heavy deformed nuclei. Giant resonances and low-energy collective states for monopole, dipole, quadrupole, and octupole modes are predicted for the heavy deformed nucleus 238 U and compared with experimental d… Show more

“…Solutions for axially deformed nuclei are |N ≡ |K , where K is the total angular momentum projection on the symmetry axis in the intrinsic frame. Details about the RPA and QRPA formalisms for spherical and axially deformed targets are provided in [11,14,15] and [12,16], respectively.…”

“…Transition potentials are calculated a e-mail: marc.dupuis@cea.fr considering rearrangement corrections [10]. Nuclear structure ingredients, namely local matter densities for the nucleus ground state (GS), as well as energy, spin, parity and local transition densities for each target excitations, are calculated within the (Q)RPA model [11,12] implemented with the Gogny D1S interaction [13].…”

“…Recently, we developed a scaled parallel Skyrme-QRPA code [10] for arbitrary axially-deformed (parity conserving) even-even nuclei. Our code is one of the few [11] to treat heavy deformed nuclei in the QRPA without simplification. (For other calculations, including those in lighter nuclei and those in the RPA, the spherical QRPA, and separable approximations, see the work cited * Present address: Center for Computational Sciences, University of Tsukuba, Tsukuba, 305-8577, Japan in Ref.…”

“…This work represents a transposition to the charge-exchange field of the fully consistent axially-symmetric-deformed QRPA calculations presented in [3] and devoted to the study of the electromagnetic excitation of deformed nuclei [4,5]. In this approach pairing correlations which play an important role in open shell nuclei are automatically included.…”

“…Consequently, pnQRPA calculations can be performed separately for each K π block. To solve the pnQRPA matrix equation we use the same numerical procedure as recently applied to the study of giant resonances of the heavy deformed 238 U [4]. This procedure is based on a massive parallel master-slave algorithm.…”
