0 The study of quark jets in e e reactions at LEP has demonstrated that the
1 hadronisation process is reproduced well by the Lund string model. However,
6 our understanding of gluon fragmentation is less complete. In this study en-
0
/ riched quark and gluon jet samples of different purities are selected in three-jet
x
e events from hadronic decays of the Z collected by the DELPHI experiment in
- the LEP runs during 1994 and 1995. The leading systems of the two kinds of
p
e jets are defined by requiring a rapidity gap and their sum of charges is studied.
h An excess of leading systems with total charge zero is found for gluon jets in
:
v all cases, when compared to Monte Carlo Simulations with JETSET (with and
i
X without Bose-Einstein correlations included) and ARIADNE. The correspond-
r ing leading systems of quark jets do not exhibit such an excess. The influence of
a
the gap size and of the gluon purity on the effect is studied and a concentration
2
of the excess of neutral leading systems at low invariant masses ( 2 GeV/c )
is observed, indicating that gluon jets might have an additional hitherto unde-
tected fragmentation mode via a two-glu
