Predicted charged charmonium-like structures in the hidden-charm dipion decay of higher charmonia
charged charmonium-like dipion decay
2011/7/21
In this work, we predict two charged charmonium-like structures close to the $D^\ast\bar{D}$ and $D^\ast\bar{D}^\ast$ thresholds, where the Initial Single Pion Emission mechanism is introduced in the ...
$Z_b(10610)$ and $Z_b(10650)$ structures produced by the initial single pion emission in the $Υ(5S)$ decays
$Z_b(10610)$ $Z_b(10650)$ 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...
Static and Dynamic Chain Structures in the Mean-Field Theory
Mean-Field Theory Static and Dynamic Chain Structures
2011/7/20
We give a brief overview of recent work examining the presence of $\alpha$-clusters in light nuclei within the Skyrme-force Hartree-Fock model. Of special significance are investigations into $\alpha$...
Study of cluster structures of excited states for the light nuclei He, Li and Be in three-body photodisintegration processes. Application for the excited states of the 6He nucleus
cluster structures light nuclei He Li excited states
2011/7/20
The method used to investigate the cluster structures of excited states for the light nuclei He, Li and Be in three-body photodisintegration processes is described. As an application we present the ex...
Quadrupole Moments of Collective Structures at Ultrahigh Spin in $^{157}$Er and $^{158}$Er: A Challenge for Understanding Triaxiality in Nuclei
Quadrupole Moments Collective Structures Ultrahigh Spin $^{157}$Er and $^{158}$Er Challenge Understanding Triaxiality Nuclei
2011/1/4
Measured transition quadrupole moments, $Q_{\rm t}{\sim}11 {\rm eb}$, of four weakly-populated collective bands at ultrahigh spin in $^{157,158}$Er demonstrate that these sequences are associated with...
Multi-quasiparticle structures up to spin $\sim{44}\hbar$ in the odd-odd nucleus $^{168}$Ta
Multi-quasiparticle structures spin $\sim{44}\hbar$ the odd-odd nucleus $^{168}$Ta
2011/1/4
High-spin states in the odd-odd nucleus $^{168}$Ta have been populated in the $^{120}$Sn($^{51}$V,3n) reaction. Two multi-quasiparticle structures have been extended significantly from spin $\sim{20\h...
Novel charmonium-like structures in the $J/\psi\phi$ and $J/\psi\omega$ invariant mass spectra
Novel charmonium-like structures
2011/1/7
Stimulated by the new evidence of Y(4274) observed in the J/ invariant mass spectrum, we first propose the charmonium-like state Y(4274) as the S-wave Ds ¯D s0(2317) + h.c. molecular state with...
Structures of N=7 and N=8 isotones with l2 coupling
shell model l2 coupling level inversion
2009/8/14
The structures of N=7 and N=8 isotones in Be-F mass range are investigated in the framework of the single-particle shell model. Different from the traditional potential terms, the l2 coupling is incl...
