Abstract:
The assumption of indistinguishability of quarks in the region of overlapping of nucleon wave functions leads to the model of joint possessing of quarks between nucleous.Besides the examination by the data of A-dependent EMC effect,the model gives the increments of average nucleon radii in various nuclei;the percentage ratios of 6-quark cluster in various nuclei,and explains the formation and dissociation of multi-quark clusters.A new possible type of fluidity of quark——"conductivity" in nuclei s predicted by the model.
