A Dependence of Longitudinal Momenta of Secondary Particles on Multiplicity in Hadronic Interactions
Abstract:
The dependence of longitudinal momenta of secondary charged particles produced in non-diffractive processes of pp collisions on the multiplicity at s=540GeV has been analyzed by using a Monte-Carlo generator of full Chou-Yang geometrical model.The re...

Abstract:
Starting from shell model configurations and effective nucleon-nucleon interactions,we proposed a microscopic approach to study the properties of high-spin states in even-even nuclei in terms of the generalized boson expansion theory.

Abstract:
SYNCH and MAD outputs in calculating lattice with coordinate rotation have been studied in this paper.The result shows that the four dispersion functions(ηx,ηx',ηy,and ηy')given by SYNCH output in this case are wrong.There are large discrepancies bet...
