O165100100022 (TOF) O165100100023 (COINC) The O-22 fragments were detected in coincidenceO165100100024 with de-exciting gamma rays.

O165100100041 CORRECTION A Doppler shift correction was made. O165100100042 COMMENT *By Authors*.The inclusive one-neutron removal cross O165100100043 section was measured by directly counting O-23 and O165100100044 O-22 in front of and behind the carbon breakup target. O165100100045 This ratio was corrected for the experimental O165100100046 transmission evaluated with the code MOCADI(see N.IwasaO165100100047 et.all, Nucl.Instrum.Methods B,126,284,1997) after O165100100048 adjusting the simulated fragment longitudinal momentum O165100100049 width to the measured one. O165100100050 The relative weight of the exclusive one-neutron O165100100051 removal cross-section involving O-22 in any excited O165100100052 states to the inclusive measurement amounts to 41+-10%.O165100100053 ERR-ANALYS (DATA-ERR) The associated error bars includes O165100100054 statistical errors, assumptions for the level scheme ofO165100100055 O-22 and uncertainties in the gamma-efficiency O165100100056 simulation.
