Abstract
During the experimental measurements a degradation in the resolution of our
quadrupole mass spectrometer caused the time-of-flight signal for Cl: (m/e= 70),
shown in fig. 4, to be contaminated with signal from the Ga+ fragmentation peaks
(m/e=69, 71) of GaCl. Careful remeasurement has revealed that the CIZ TOF
are perfectly described by a prompt single Maxwell-Boltzmann component at the
surface temperature. There is thus no evidence of time-delayed CIZ production.
All other data on the GaCl,/GaCl temperature profiles, GaCl angular distribu-
tion, and the observation of two-components in the GaCl TOF are correct. The
discussion is modified to the extent that reference to delayed Cl, production and
the tentative considerations of the nature of the link between delayed Cl* pro-
duction and GaCl production are no longer relevant.
