Dear Sirs,
I am Maurizio De Sanctis, Associate Professor of Universidad Nacional de Colombia,
Departamento de F?sica Sede Bogot?; I have been Researcher of INFN, Rome Italy,
until July 2008.
I wrote you some days ago (September 24) from my personal e-mail address but I did not
receive an answer with the moderator's decision.
(See a copy of those messages in the attachment)
What shall I do to get an answer?
Probably my previous message was not sufficiently clear and I did not properly inform you about my position and activities. I apologyze and pass to my questions.
My research activities are mainly focussed on theoretical models of hadronic particles.
I am working on this subject, with some students, in the framework of the
Fields and Particles research group of the Physics Department.
Two months ago I started to use Maxima for my calculations. I think that it
really represents a very important tool for my research and teaching activity
of the Physics Department to which I belong.
The questions are:
1) Does it exist (and can you send me) a package of routines about
Angular Momentum Algebra in Quantum Mechanics ? As a reference, this subject has been widely developed in the standard book by Edmonds, Angular Momentum in Quantum Mechanics. A number of tedious but conceptually straightforward calculations are usually required.
Maxima seems the best tool to perform efficiently these calculations.
At least, is there a routine for the Clebsch-Gordan (or Wigner 3j) coefficients?
2) Up to now I am running my (short) Maxima programs on my PC (with Windows XP).
I would like to install Maxima in the computer of the Physics Department.
This computer uses a LINUX OS. The system manager found some difficulties in the
installing procedure. Can you give use some suggestions about this point ?
Many thanks and best regards
Maurizio De Sanctis
