Abstract: | In this paper,we obtain the expressions of electromagnetic current,charged current,baryon current and neutral weak current in the Skyrme model by means of the gauge transformations.A relation available for both cases of mπ=0 and mπ≠0 is given.The mean square radius < r2 >A of axial form factor is calculated and the result shpws that its value is much smaller than the experimental datum.In addition,the expressions of < r2 > M,T=l and < r2 >M,T=0 in our derivations are different from those given in Ref.[4] by a factor 3/5. |
