A study of charm fragmentation into D{sub s}{sup *+} and D{sub s}{sup +} in e{sup +}e{sup -} annihilations at {radical}(s)=10.5 GeV is presented. This study using 4.72{+-}0.05 fb{sup -1} of CLEO II data reports measurements of the cross sections {sigma}(D{sub s}{sup *+}) and {sigma}(D{sub s}{sup +}) in momentum regions above x=0.44, where x is the D{sub s} momentum divided by the maximum kinematically allowed D{sub s} momentum. The D{sub s} vector to vector plus pseudoscalar production ratio is measured to be P{sub V}(x(D{sub s}{sup +})>0.44)=0.44{+-}0.04. (c) 2000 The American Physical Society.
