$Z_b(10610)$ $Z_b(10650)$ initial single pion emission
2011/7/21
We propose an unique mechanism called {\it Initial Single Pion Emission} existing in the $\Upsilon(5S)$ decays, and further study the line shapes of $d\Gamma(\Upsilon(5S\to \Upsilon(nS)\pi^+\pi^-))/dm...

The fast-stage nucleon emission of proton-nucleus (pA) reactions from 300A MeV to 1.8A GeV has been investigated using the quantum molecular-dynamics model. It is found that the sideward angular spect...
Half-lives and branchings for β-delayed neutron emission for neutron-rich Co-Cu isotopes in the r-process
Half-lives branchings β-delayed neutron emission neutron-rich Co-Cu isotopes the r-process
2010/12/31
The {\beta} decays of very neutron-rich nuclides in the Co-Zn region were studied experimentally at the National Superconducting Cyclotron Laboratory using the NSCL {\beta}-counting station in conjunc...
Measurements of nuclear $\gamma$-ray line emission in interactions of protons and $\alpha$ particles with N, O, Ne and Si
Measurements of nuclear $\gamma$-ray line emission interactions of protons $\alpha$ particles with N, O, Ne and Si
2011/1/4
$\gamma$-ray production cross sections have been measured in proton irradiations of N, Ne and Si and $\alpha$-particle irradiations of N and Ne. In the same experiment we extracted also line shapes fo...
Limiting soft particle emission in e+e-, hadronic and nuclear collisions
particle emission hadronic e+e- nuclear collisions
2010/3/16
In e+e- collisions the particle spectra at low momenta reflect the properties of the underlying "soft" QCD gluon bremsstrahlung: the particle density, in the limit p\to 0, becomes independent of the i...
Langevin study of neutron emission in the reactions 16O+181Ta and 19F+178Hf
pre-scission neutron multiplicity entrance channel mass asymmetry compound nucleus spin distribution Langevin equation
2009/8/14
The pre-scission neutrons measured in the reactions 16O+181Ta and 19F+178Hf are studied via a Langevin equation coupled with a statistical decay model. We find that because of the mass asymmetry of di...
Development of a facility for research of charged particle emission induced by fast neutron reactions
intermediate energy neutron (n x) reaction ΔE-ΔE-E telescopes
2009/8/14
A facility has been constructed for research of charged particle emissioninduced by fast neutron reactions ((n, x) reaction) based on the whiteneutron source and the quasi-monoenergetic neutron source...
Effect of entrance-channel asymmetry on the isospin dependence of nucleon emission in heavy ion collisions
neutron to proton ratio symmetry energy isospin asymmetry of reaction system hadronic transport model
2009/8/14
Using the isospin- and momentum-dependent hadronic transport model IBUU04, we have investigated the influence of the entrance-channel isospin asymmetry on the sensitivity of the pre-equilibrium neutro...
