  The half-life of the 2 neutrino double-beta-decay of 160Gd, a process which
was previously reported as theoretically forbidden, is estimated by including
the pairing interaction, which mixes different occupations and opens channels
for the decay. Explicit expressions are presented for the pairing mixing, and
for the 2 nu and 0 nu double-beta-decay nuclear matrix elements in the present
pseudo SU(3) approach. The estimated double-beta-decay half-lives suggest that
the planned experiments would succeed in detecting the 2 nu double-beta-decay
in 160Gd, and in putting competitive limits for the zero neutrino mode.
