  • 9 Dec. 2002: Version 2 of my bubblegum code to do two-channel analytic and unitary resonance analysis is now freely available.
    (The accompanying paper is published in Phys.Rev. C (PRC 67, 035203).)

  • 22 April 2003: The full-color Dalitz plots of two-pion production kinematical diagrams, as seen in B/W in nucl-th/0304072.

    • 5 April 2003:
  • SHY My Fortran code for calculating spherical harmonics.

    • There are in principle no limits on L and M (Abs(M) LE L). At the moment the array limit is set at 256 terms in the polynomial, which corresponds to L=30 for small M and L=22 for M=11 or so. It is of little consequence to make the arrays much bigger.
    It consists of a number of subroutines:
    Y generates a list of terms which is a polynomial in x, y, and z, of a normalized solid spherical harmonic r^l Y_lm.
    PRNTY prints a spherical harmonic to be used in other codes.
    MATEL calculates the matrix elements < L,M| x^k y^n z^p |L',M'> fast with typical 14-15 decimals precision (for orthogonality, a couple less for general matrix elements).

  • PaLIS (Point and Line Interpolated Surfaces) An algorithm to generate smooth organic forms given limited global information. eight surfaces, large rigidity, control points are the centers of the surfaces

  • The Zoef approach to PDF (portable document format) notes on PDF .
