  The results of investigation of Xe-127 radioactive isotope production in the
xenon sample enriched in Xe-124, Xe-126, Xe-128 are presented. The isotope is
supposed to be the source of the background events in the low-background
experiment on search for 2K-capture of Xe-124. In this work we consider two
channels of Xe-127 production: the neutron knock-out from Xe-128 nucleus by
cosmogenic muons and the neutron capture by Xe-126 nucleus. For the first
channel the upper limit of the cross section of Xe-127 production was found to
be sigma >= 0.007 barn at 95\% C.L. For the second channel the value obtained
for the cross section was found to be equal to sigma =(2.74+-0.4) barn, which
coincides well, within the statistical error, with reference value.
