2050076 We studied the charge radius ($r_{c}$), neutron radius ($r_n$), and neutron
skin-thickness ($\Delta r=r_n-r_p$) over a chain of isotopes from C to Zr with
the stable region to the neutron drip line. Theoretical calculations are done
with axially deformed self-consistent relativistic mean-field theory (RMF) with
effective nonlinear NL3 and NL3* interactions. The theoretically estimated
values are compared with available experimental data and a reasonable agreement
are noted. We additionally assessed the two-neutron separation energy
($S_{2n}$) to mark the drip line nuclei of the considered isotopic series. In
the reference of $S_{2n}$, neutron magicity is also discussed. The calculated
neutron radii are compared with empirical estimation made by $r=r_0N^{1/3}$ to
examine the abnormal trend of the radius for neutron drip line nuclei. In view
to guide the long tails, the density distribution for some skin candidates is
analyzed. Finally, neutron skin thickness is observed for the whole considered
isotopic series.
