The transverse distributions of energy in family events observed by emulsion chambers at Mt. Kanbala are showed in comparison with Monte Carlo simulations. Analysis indicates that a character of energy concentration exists in ultra high energy famili...

Abstract:
A method for measuring the integrated luminosity of the e+ e－ colliding experiment by using the wide-angle Bhabha events at the center of mass energy of the ψ(2S) resonance is presented. The determination of the integrated luminosity for the ψ(2S) da...

Abstract:
The non-diagonal solutions to the reflection equation of 15 vertex model A2(1) model and supersymmetric t-J model were obtained. The results show that solutions of A2(1) model' have three forms and each form contains two solutions; the solution of su...

Abstract:
We present the constant solutions with all matric elements non-Vanishing to the reflection equation of 19 vertex model-A2(1) model. Some nondigonal solutions are also obtained.

Abstract:
The emission time of intermediate mass fragments (IMF) has been studied as a function of spatial evolution of the emission source for 40Ar+natAg reaction at 30MeV/u, and the spatial-time evolution of projectile-like fragments emission has also been d...

Abstract:
The angular & Z distributions of foe fragments emitted in the forward and intermediary angles are measured at the reaction of 25 MeV/u 40Ar+115In,58Ni,27Al. Their characteristics are investigated based on the model of Modified Qantum Molecular Dynami...

Abstract:
We have investigated the yield and the spectrum of the K－ mesons in the heavy-ion collisions with the relativistic RBUU approach. It's found that the ratio of the yield of K+ to K－ depends on the size of the nuclear systems. One main reason is caused...

Abstract:
Microcanonical simultaneous multifragmentation statistical model was used to analyse the ALADIN caloric curue. It is indicated that each theoretical representative point located in the temperature plateau (temperature backhanding) of ALADIN caloric c...

Abstract:
The △I= 1 staggering is investigated for the superdeformed bands observed in the doubly odd nuclei 150,152Tb,144,148Eu and 130,132Pr. The spin values of these bands are assigned from the ab-and modified ah-fitting. The possible mechanism and the inhe...

Abstract:
The spins of superdeformed bands in A≈150 region are assigned by the ah fitting provided the fluctuation are removed from the observed transition energies. Some typical superdeformed bands are discussed. For some superdeformed bands, the precision of...

Abstract:
The ratio between the coherent and incoherent densities of a coherent harmonic generation FEL is proportional to the square of the modulation rate of the spontaneous emission spectrum of its optical klystron. Therefore enhancing the modulation of the...

Abstract:
In the Paper we give some results about nuclear shadowing of real photon at LHC. We show that shadowing grows strong with the increasing of Photon energy Eγ. The CMS energy dependence of total cross sections of production of ρ,ω and φ in the process ...
