A Self-affine fractality analysis was performed by using the experimental data of multiparticle production in pp collisions at 400GeV/c. Compared with the results obtained from the selfsimilar analysis, the self-affine fractality analysis shows a bet...

Abstract:
The perturbative QCD prediction of “15% rule” for the ratio of ψ(2S) to J/ψ hadronic decay rates suffers seveal apparent approximations. Calculations using existing experimental data are made in this paper; further corrections to this radio for a num...

The high spin states in 126Ba were populated by means of the reaction 116Sn (16O,2p4n)126Ba at the beam energy of 73MeV. Lifetimes of the states around the backbend in the yeast band were measured by using the Doppler shift attenuation method. The co...

The neutron yields and the neutron emission rates in the forward direction for 50MeV/u 18O-ion induced reactions on thick Be, Cu, Au targets have been measured using the threshold detector activation method. The measured results indicate that the neu...

The probability of Color Rearrangement at partonic level in e+e-→W+W-→h,s process is studied using the Color Effective Hamiltonian. The comparison between our results and those of Gutafson and Sjostrand et al. is also given. It is found that this pro...

In Order to extend the conventional shell model(SM) calculation with harmonic oscillator bases to halo nuclei, a self-similar, structure shell model(SSM) is proposed. The SSM is achieved by a rescaling of both the Kinetic and potential energy term of...

The increase of effective string tension as a result of the hard gluon kinks on a string is investigated using a parametrization form. In this form the effective string tension increasing with energies in hadron-hadron collisions is due to the mini-j...

Introducing the staggering index S(I) to describe the energy spectra of the λrigid and λ-soft nuclei, it becomes very clear that there are two kinds of energy staggering for which the S(I) -I plots have opposite zigzag behavior. They can be described...
