## Properties of SHE

Superheavy elements in framework of Skyrme(SkM*) HFB theory

## Description

The results presented here were originally posted at "http://kft.umcs.lublin.pl/edf/" and were obtained in cooperation with A. Staszczak (UMCS Lublin, PL) and W. Nazarewicz (ORNL Oak Ridge, USA).

There are shown ground state (GS) properties and the
barrier heights (V_{A}) for some superheavy
nuclei in the region Z=108-126 and N=148-188.

We are using the Skyrme SkM* force and the following
definition of the quadrupole moment:
q_{20} =
Σ< x^{2} + y^{2} - 2z^{2}>.

UNITS:

[q_{20}] = barn; [Energy] = MeV;
[Mass parameter] = hbar/(MeV b^{2});
[Moment of inertia] = hbar/MeV;
[rms radii] = fm;
[Half life] = year

Mass parameters were calculated either from cranking
formulae in HFB basis (cp) or in canonical basis
(cpc). The HFB energy (potential) was either corrected
for zero point energy (zpe) or it was taken as
is. Therefore, there are four possible combinations of
final results: *cp, cpc, cp-zpe and cpc-zpe*.
One can choose the proper model in 'The Model' option list.

By clearing the plot (click the Clear button) and clicking on the name of the serie in the LEGEND of the chart you can plot the single curve for a given isotopic chain Z. Pointing the data on a curve you can get the exact numbers for a given data point in Tooltip window.

Cicking on a label in **the legend** of the chart
one can switch the series off or on. With a mouse
pointer, the zooming is performed by dragging out a
rectangle in the chart.
