Skyrme-Hartree-Fock results for Phosphorus 27


* Last modification (y/m/d):2011/11/18
This directory contains the results of Hartree-Fock calculations for Phosphorus 27: 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 except for two cases. The temperature is exactly zero for all the calculations except for excited solutions with Msk7 and SkSC4 forces.
  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.)
