  First results of ALICE on the production of nuclei and antinuclei in pp
collisions at \surd s = 7 TeV are presented. These particles are identified
using the energy loss (dE/dx) measurements in the Time Projection Chamber. The
Inner Tracking System allows a precise determination of the event vertex, by
which primary and secondary particles are well separated. The high statistics
of over 350 M events give a significant number of light nuclei and antinuclei
such as (anti)deuterons, (anti)tritons, (anti)Helium3 and possibly
(anti)hypertritons. The study of nuclei and antinuclei will help to understand
their production mechanisms. Antinuclei production as a function of particle
multiplicity in an event is discussed in this respect. Various particle ratios
obtained from these collisions using predictions from a statistical model are
also presented.
