(************** Content-type: application/mathematica ************** Mathematica-Compatible Notebook This notebook can be used with any Mathematica-compatible application, such as Mathematica, MathReader or Publicon. The data for the notebook starts with the line containing stars above. To get the notebook into a Mathematica-compatible application, do one of the following: * Save the data starting with the line of stars above into a file with a name ending in .nb, then open the file inside the application; * Copy the data starting with the line of stars above to the clipboard, then use the Paste menu command inside the application. Data for notebooks contains only printable 7-bit ASCII and can be sent directly in email or through ftp in text mode. Newlines can be CR, LF or CRLF (Unix, Macintosh or MS-DOS style). NOTE: If you modify the data for this notebook not in a Mathematica- compatible application, you must delete the line below containing the word CacheID, otherwise Mathematica-compatible applications may try to use invalid cache data. For more information on notebooks and Mathematica-compatible applications, contact Wolfram Research: web: http://www.wolfram.com email: info@wolfram.com phone: +1-217-398-0700 (U.S.) Notebook reader applications are available free of charge from Wolfram Research. *******************************************************************) (*CacheID: 232*) (*NotebookFileLineBreakTest NotebookFileLineBreakTest*) (*NotebookOptionsPosition[ 4269, 161]*) (*NotebookOutlinePosition[ 5575, 202]*) (* CellTagsIndexPosition[ 5447, 195]*) (*WindowFrame->Normal*) Notebook[{ Cell[CellGroupData[{ Cell["Doing Spin Sums I", "Subtitle", TextAlignment->Center, TextJustification->0], Cell["\<\ In this notebook, we evaluate the spin sums for the lowest-order \ diagrams for a spin-independent delta function potential.\ \>", "Text"], Cell["\<\ Programmer: Dick Furnstahl furnstahl.1@osu.edu\tRevision history: \ 08-Feb-2003 --- original version for 880.05\ \>", "Text"], Cell[CellGroupData[{ Cell["Load simplification package", "Subsection"], Cell["\<\ The package is assumed to be in the same directory as this \ notebook.
