Abstract
We calculate g(A)((3)) and g(A)((0)) in the chiral quark-soliton model (or equivalently in semibosonized Nambu-Jona-Lasinio model) in the li mit of small and large soliton size. In small soliton limit we recover the results of the constituent quark model. The agreement between the two models is achieved due to the recently calculated 1/N-c contribut ions to g(A)((3)) and to g(A)((0)). In the case of g(A)((3)) these ter ms arise from the rime-ordering of the collective operators. For large solitons simple scaling arguments show that the 1/N-c contributions v anish with the inverse power of the soliton size.
