Table 2 contains abundances obtained from least-square fittings for normal stars with metallicities corresponding to our sample of barium stars. first line of the set corresponds to the logarithm of the total abundance (log(eps(X))) determined directly from the least square fittings. The second line corresponds to the abundance fraction (epsilons(X)) relative to the s-process main component, and the third and forth lines correspond to the abundance fractions relative to the r- and p-processes (epsilonr(X) epsilonp(X)), respectively. The last line corresponds to the sum of abundances from other processes except the s-process main component.
Table 6 contains the results of the abundance distribution for the s-, r-, and p-processes for the sample of barium stars and abundance fractions of the s-process main component for normal stars. sigmaN and sigmaN(Si): cross-section times abundance fraction corresponding to the s-process main component taking the overabundance of barium stars into account on the usual scale and Si scale, respectively; sigmaN(gs): cross-section times abundance fraction corresponding to the s-process main component without the overabundance of barium stars, i.e., by using the solar distribution on the total abundance.
