Abstract:
Using SEST, the Parkes antenna and the Australia Telescope Compact
Array, we have made a survey of the 12CO(1-0) and HI emission of an
optically-selected sample of ≃60 southern interacting and merging
galaxies. In this paper we present the data and determine global
masses of neutral gas (in molecular and atomic form) for the observed
galaxies. We have detected HI in 26 systems and found that
these galaxies have less than 15% of their gas in molecular form.

Description of Figures (*.ps files):
--------------------------------------------------------------------------------
Column 1: contour and grey-scale pictures of the galaxies (ESO Digitized
Sky Survey). North is to the top, west to the right.
The scales on the axes are in arcsec.
Column 2: HI spectra. The spectral resolution is 6.6km/s. The units are km/s
on the X axis (radial velocities in the radio convention) and
Jy on the Y axis.
Column 3: CO spectra. The spectral resolution is 14.6km/s. The units are km/s
on the X axis (radial velocities in the radio convention) and
K on the Y axis (TA*).
When the two galaxies of a pair were observed, the two spectra are shown and
the name of the observed galaxy is given close to the corresponding spectrum.
The lower spectrum refers to the most southern galaxy on the
optical image, the upper one to the other.
