Abstract
It is shown that the orbifold of type IIB string theory by (-1)(FL) f(4) ad mits a stable non-BPS Dirichlet particle that is stuck on the orbifold fixe d plane. It is charged under the SO(2) gauge group coming from the twisted sector, and transforms as a long multiplet of the D = 6 supersymmetry algeb ra. This suggests that it is the strong coupling dual of the perturbative s table non-BPS state that appears in the orientifold of type IIB by Omega f( 4). (C) 1998 Published by Elsevier Science B.V.
