Description

We analyse the binding energy and charge distribution radius for the
latest superheavy nuclei synthesized in various laboratories, with atomic numbers
$Z=110-118$. For this calculation we use extended Thomas-Fermi approximation
within the relativistic mean field framework. The binding energy and radii are
compared with the results obtained from relativistic Hartree calculations along with
the experimental data, wherever available, to check the reliability of the methods.
The calculations are extended to estimate the giant monopole resonances to
understand the collective vibration of the nucleons for such superheavy nuclei. The
giant monopole resonances obtained from scaling calculations are compared with
the constraint computations. Furthermore, the results are compared with other
known methods, such as the relativistic Random Phase Approximation (RPA) and
time-dependent mean field calculations along with some known lighter nuclei,
specifically Zr isotopes (N=42-86) and O-isotopes (N=10-36). Finally, the nuclear
compressibility of the superheavy nuclei are predicted from the obtained breathing
mode energy.
