  We consider closed-string tachyon condensation in the twisted sectors on the
C/Z_{2n+1} \times R^{7,1} orbifold. We calculate the localized energy density
in the fixed plane on the orbifold at the one-loop level, and we obtain the
decay rate per unit volume of the fixed plane to leading order. We show that
the decay rate increases monotonically as a function of n.
