Abstract:
The effect of the evolution of partons in nuclear environment to the structure function of nucleons bound in a nucleus is investigated.Together with the nuclear shadowing effect caused by the spatial overlap of partons from neighboring nucleons in th...

Abstract:
We have calculated the energy spectra of the hypernucleus 9Be up to about 15MeV excitation energy by using an α+α+Λ three-cluster model and using the hamonicoscillator product states as basis function.By analyzing the shape densities in detail,we hav...

Abstract:
Some parameters and the β equation of Johansson mass formula were modified.In the fit to the experimental masses and two-neutron separation energies (S2n) of 640 nuclides in the region of 50≤Z≤71,four free parameters are presented.The root-mean-squar...
