One nucleon transfer operator and nuclear supersymmetry
(American Physical Society, 2005-01-01)
The appropriate use of the interacting boson-fermion model one nucleon transfer operator in connection with nuclear supersymmetries is discussed. We emphasize that care must be taken in using the same coupling ...

Be 9 elastic scattering on Pb 208 and Al 27 within a four-body reaction framework
(American Physical Society, 2015)
We investigate low-energy Be9 elastic scattering on two different targets (heavy, light) within a four-body framework using the continuum-discretized coupled-channels (CDCC) method. The Be9 projectile is described in an ...

Particle motion in a deformed potential using a transformed oscillator basis
(American Physical Society, 2012)
The quantum description of a particle moving in a deformed potential is investigated. A pseudostate (PS) basis is used to represent the states of the composite system. This PS basis is obtained by diagonalizing the system ...

Analytical transformed harmonic oscillator basis for continuum discretized coupled channels calculations
(The American Physical Society, 2009)
A new method for continuum discretization in continuum-discretized coupled-channels calculations is proposed. The method is based on an analytic local-scale transformation of the harmonic-oscillator wave functions proposed ...

Relation between E(5) models and the interacting boson model
(The American Physical Society, 2008)
The connections between the E(5) models [the original E(5) using an infinite square well, E(5)-β4, E(5)-β6, and E(5)-β8], based on particular solutions of the geometrical Bohr Hamiltonian with γ-unstable potentials, and ...

Prealignment B(E2)-anomaly in 124Xe
(Elsevier, 1983)
Lifetimes of 17 levels of 124Xe were measured using the Recoil Distance Doppler Shift method. An anomalous E2-reduction was observed, starting at Iπ = 8+ and Iπ = 5+ in the groundstate and in the quasi-gamma band respectively. ...

Four-body continuum-discretized coupled-channels calculations using a transformed harmonic oscillator basis
(The American Physical Society, 2008)
The scattering of a weakly bound three-body system by a target is discussed. A transformed harmonic oscillator basis is used to provide an appropriate discrete and finite basis for treating the continuum part of the spectrum ...

Continuum coupling in one-dimensional scattering using a transformed harmonic oscillator basis
(American Physical Society, 2002)
The continuum coupling in a one-dimensional scattering problem was studied within a semiclassical approach by means of a transformed harmonic oscillator (THO). The THO basis provided a finite set of normalized states ...

Search for critical-point nuclei in terms of the sextic oscillator
(The American Physical Society, 2010)
The spherical to deformed γ-unstable shape transition in nuclei is discussed in terms of the sextic oscillator as a γ-independent potential in the Bohr Hamiltonian. The wave functions, energy eigenvalues, and electric ...

At the Borderline of Shape Coexistence: Mo and Ru
(American Physical Society, 2023)
Background: Even-even isotopes of Mo (Z=42) and Ru (Z=44) are nuclei close to the subshell closure at Z=40, where shape coexistence plays a significant role. As a result, their spectroscopic properties are expected to ...
