Abstract
A study of charm fragmentation into D-s(*+) and D-s(+) in e(+)e(-) annihila tions at root s = 10.5 GeV is presented. This study using 4.72 +/- 0.05 fb( -1) of CLEO II data reports measurements of the cross sections sigma(D-s(*))) and sigma(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 +/- 0.04.
