  The evaporation residue of Barium isotopes are investigated in a microscopic
study using relativistic mean field theory. The investigation includes the
isotopes of Barium from the valley of stability to exotic proton-rich region.
The ground as well as neck configurations for these nuclei are generated from
their total nucleonic density distributions of the corresponding state. We have
estimated the constituents (number of nucleons) in the elongated neck region of
the fission state. We found the $\alpha$-particle as the constituent of neck of
Ba-isotopes, referred to as the evaporated residue in heavy-ion reaction
studies. A strong correlation between the neutron and proton is observed
throughout the isotopic chain.
