We present the results on the distribution and kinematics of H\sc{i} gas
with higher sensitivity and in one case of higher spectral resolution as well
than reported earlier, of three irregular galaxies CGCG 097073, 097079 and
097087 (UGC 06697) in the cluster Abell 1367. These galaxies are known to
exhibit long (50−75 kpc) tails of radio continuum and optical emission lines
(Hα) pointing away from the cluster centre and arcs of starformation on
the opposite sides of the tails. These features as well as the H{\sc i}
properties, with two of the galaxies (CGCG 097073 and 097079) exhibiting
sharper gradients in H{\sc i} intensity on the side of the tails, are
consistent with the H{\sc i} gas being affected by the ram pressure of the
intracluster medium. However the H{\sc i} emission in all the three galaxies
extends to much smaller distances than the radio-continuum and Hα tails,
and are possibly still bound to the parent galaxies. Approximately 20−30 per
cent of the H{\sc i} mass is seen to accumulate on the downstream side due to
the effects of ram pressure.Comment: 19 pages, 19 figures, 3 tables, accepted for publication in the
