Query: Isotopic yield in cold binary fission of even-even $^{244-258}$Cf
  isotopes   The cold binary fission of even-even 244-258Cf isotopes has been studied by
taking the interacting barrier as the sum of Coulomb and proximity potential.
The favorable fragment combinations are obtained from the cold valley plot
(plot of driving potential vs. mass number of fragments) and by calculating the
yield for charge minimized fragments. It is found that highest yield for
244,246,248Cf isotopes are for the fragments with isotope of Pb (Z=82) as one
fragment, whereas for 250Cf and 252Cf isotopes the highest yield is for the
fragments with isotope of Hg (Z=80) as one fragment. In the case of
254,256,258Cf isotopes the highest yield is for the fragments with Sn (Z=50) as
one fragment. Thus, the fragment combinations with maximum yield reveal the
role of doubly magic and near doubly magic nuclei in binary fission. It is
found that asymmetric splitting is favoured for Cf isotopes with mass number A
< 250 and symmetric splitting is favoured for Cf isotopes with A > 252. In the
case of Cf isotope with A=252, there is an equal probability for asymmetric and
symmetric splitting. The individual yields obtained for the cold fission of
252Cf isotope are compared with the experimental data taken from the {\gamma}-
{\gamma}- {\gamma} coincidences technique using Gammasphere.
