Charge radii and electromagnetic moments of Li and Be isotopes from the ab initio no-core shell model
C. Forssén, E. Caurier, P. Navrátil
Recently, charge radii and ground-state electromagnetic moments of Li and Be isotopes were measured precisely. We have performed large-scale ab initio no-core shell model calculati…
The ab initio no-core shell model
C. Forssen, J. Christensson, P. Navratil +4
This contribution reviews a number of applications of the ab initio no-core shell model (NCSM) within nuclear physics and beyond. We will highlight a nuclear-structure study of the…
Converging sequences in the ab initio no-core shell model
C. Forssén, J. P. Vary, E. Caurier +1
We demonstrate the existence of multiple converging sequences in the ab initio no-core shell model. By examining the underlying theory of effective operators, we expose the physica…
Two-proton radioactivity and three-body decay. IV. Connection to quasiclassical formulation
L. V. Grigorenko, M. V. Zhukov
We derive quasiclassical expressions for the three-body decay width and define the ``preexponential'' coefficients for them. The derivation is based on the integral formulae for th…
Two-proton radioactivity and three-body decay. III. Integral formulae for decay widths in a simplified semianalytical approach
L. V. Grigorenko, M. V. Zhukov
Three-body decays of resonant states are studied using integral formulae for decay widths. Theoretical approach with a simplified Hamiltonian allows semianalytical treatment of the…
Determining neutron-capture cross sections via the surrogate reaction technique
C. Forssen, F. S. Dietrich, J. Escher +2
Indirect methods play an important role in the determination of nuclear reaction cross sections that are hard to measure directly. In this paper we investigate the feasibility of u…
