Abstract

A study of charm fragmentation into

D_{s}^{* +}

and

D_{s}^{+}

in

e^{+} e^{-}

annihilations at

\sqrt{s} = 10.5 GeV

is presented. This study using

4.72 \pm 0.05 {fb}^{- 1}

of CLEO II data reports measurements of the cross sections

σ {(D}_{s}^{* +})

and

σ {(D}_{s}^{+})

in momentum regions above

x = 0.44,

where x is the

D_{s}

momentum divided by the maximum kinematically allowed

D_{s}

momentum. The

D_{s}

vector to vector plus pseudoscalar production ratio is measured to be

P_{V} {(x (D}_{s}^{+}) > 0.44) = 0.44 \pm 0.04.
