Query: Role of Fragment Higher Static Deformations in the Cold Binary Fission
  of $^{252}$Cf   We study the binary cold fission of $^{252}$Cf in the frame of a cluster
model where the fragments are born to their respective ground states and
interact via a double-folded potential with deformation effects taken into
account up to multipolarity $\lambda=4$. The preformation factors were
neglected. In the case when the fragments are assumed to be spherical or with
ground state quadrupole deformation, the $Q$-value principle dictates the
occurence of a narrow region around the double magic $^{132}$Sn, like in the
case of cluster radioactivity. When the hexadecupole deformation is turned on,
an entire mass-region of cold fission in the range 138 - 156 for the heavy
fragment arise, in agreement with the experimental observations.
  This fact suggests that in the above mentioned mass-region, contrary to the
usual cluster radioactivity where the daughter nucleus is always a
neutron/proton (or both) closed shell or nearly closed shell spherical nucleus,
the clusterization mechanism seems to be strongly influenced by the
hexadecupole deformations rather than the $Q$-value.
