  We have employed RMF+BCS (relativistic mean-field plus BCS) approach to study
behaviour of pf shell with the help of ground state properties of even-even
nuclei. Our present investigations include separation energies , deformations,
single particle energies, wavefunction, potential as well etc density
distribution. As per recent experiments showing neutron magicity at N = 32 for
Ca isotopes, our results with mass dependent pairing indicate a shell closure
at N = 32 in Ca isotopes and a more strong shell closure at N = 34 in proton
deficient 48Si because of reorganization of neutron pf shell. In a similar
manner, proton pf shell structure is more likely to produce shell closure at Z
= 34 with a doubly magic character for 84,116Se. We have also included N = 40
isotones and Z = 40 isotopes for our study and predicted 60Ca and 68Ni as
doubly magic nuclei out of which 60Ca is found near dripline of Ca and a
potential candidate for future studies in the chain of Ca isotopes next to
doubly magic 52Ca.
