Skyrme-Hartree-Fock results for 17 Neon

* Last modification (y/m/d):2011/11/17,18,19
This directory contains the results of Hartree-Fock calculations for Neon 17: HF calculations were done with the Skyrme Msk7, S3, SG2, SkM*, SkSC4, and SLy4 forces in the Catresian-mesh representation with a mesh spacing of 0.5fm and a cubic box=0.5fm*(50,50,50). (i.e., the length of the edge is 25 fm.) An octant of a nucleus is placed at a corner of the box, imposing D_{2h} symmetry. Nearest boundary is located at 25 fm from the center of the nucleus. The furtherst point in the box is located at 25fm*sqrt(3) from the center of the nucleus.

explanations

  1. "energy" is the binding energy of the nucleus compared with separated protons and neutrons.
  2. Qz=2z^2-x^2-y^2, i.e., the mass quadrupole moment, where z-axix is the symmetry axis.
  3. "gamma" is axial asymmetry parameter of the mass distribution. (in degree. +/-180deg and 0deg is the same)
  4. Click "detail" for the output of the program
    These output contains a character string "T=50keV" (meaning temperature is 50keV) which is not true. The temperature is exactly zero for all the calculations.
  5. Click "RDP" for the angle-averaged radial density profile data. Data columns are :
    1. radius(fm)
    2. nucleon density(1/fm^3)
    3. neutron density(1/fm^3)
    4. proton density(1/fm^3)
    5. the number of mesh points to calculate the values in columns (1)-(4) as arithmetic averages
    Use a specialized interporation program to make an equidistant spacing radial density profile data using nonuniform mesh data obtainable by clicking "RDP"
  6. [NC] means that the solution has not been converged yet but is oscillating in configuration. (A finite temperature will stop the oscillation and make the solution converged.)
