This directory "/hfs3" contains files concerning a paper "Extensive Hartree-Fock + BCS calculation with Skyrme SIII force" written by N. Tajima, S. Takahara, and N. Onishi published in Nuclear Physics A603 (1996) 23 .

Following is the abstract of the paper:

We have performed deformed Hartree-Fock+BCS calculations with the Skyrme SIII force for the ground states of even-even nuclei with 2 <= Z <= 114 and N ranging from outside the proton drip line to beyond the experimental frontier in the neutron-rich side. We obtained spatially localized solutions for 1029 nuclei, together with the second minima for 758 nuclei. The single-particle wavefunctions are expressed in a three-dimensional Cartesian-mesh representation, which is suitable to describe nucleon skins, halos, and exotic shapes as well as properties of ordinary stable nuclei. After explaining some of the practical procedures of the calculations, we compare the resulting nuclear masses with experimental data and the predictions of other models. We also discuss the quadrupole (m=0, 2) and hexadecapole (m=0, 2, 4) deformations, the skin thicknesses, the halo radii, and the energy difference between the oblate and the prolate solutions. Our results can be obtained via computer network.
The contents of the subdirectories are as follows. For more information, see a file named "read.me" put in each subdirectory.

(1) ./paper

Latex source file for the paper and postscript files for figures appearing in the paper.

(2) ./table

Data tables of various quantities for the ground states and the lowest shape isomers of 1029 even-even nuclei calculated in this paper.

(3) ./output

Output files of the HF+BCS code "EV8" with Skyrme SIII force. There are 3767 files, i.e., we tried 3767 calculations searching for various-shape solutions of 1029 nuclei.

IMPORTANT INSTRUCTIONS concerning files in "./output"

Do not try to see the list of files in the directory /hfs3/output using ftp commands "ls" or "dir" because, then ,you have to see 3770 lines on your screen. Instead, get a file named "filelist" and read it on your computer. All the other files are the output files and have names matching "n???????.res.gz". Do not try to get all these output files with the ftp command "mget *" because it will cause too heavy traffic in the network.

(4) ./program

This directory contains fortran source programs ("*.for") and the explanations of the program ("*.txt"). Some of these files may be useful to analyze output files given in "/hfs3/output" and others for more general purposes.
