Unitary coupled-channels model for three-mesons decays of heavy mesons
heavy-meson hadronic decay exotic meson 3-body unitarity
2011/7/21
A unitary coupled-channels model is presented for investigating the decays of heavy mesons and excited meson states into three light pseudoscalar mesons. The model accounts for the three-mesons final ...
Alpha-Cluster Model, Charge Symmetry of Nuclear Force and Single Particle Bound State Potential in Symmetrical Nuclei
Alpha-Cluster Model Nuclear Force Bound State Potential
2011/7/20
A phenomenological alpha-cluster model based on the charge symmetry of nuclear force allows one to estimate the last proton position radius (LPPR) in a symmetrical nucleus. The values of LPPR obtained...
Collective versus Single--Particle Motion in Quantum Many--Body Systems from the Perspective of an Integrable Model
Single--Particle Motion Quantum Many--Body Systems Integrable Model
2010/4/8
We study the emergence of collective dynamics in the integrable Hamiltonian system of two finite ensembles of coupled harmonic oscillators. After identification of a collective degree of freedom, the ...
Shell-model studies of isomeric states in 51,52,53Fe
CD-Bonn potential shell model Fe isomer
2009/8/14
The yrast bands of 51,52,53Fe have been studied with a microscopical effective Hamiltonian derived from the charge-dependent Bonn NN potential. Calculations obtain satisfactory agreements with experim...
