The Virginia Tech Partial-Wave Analysis Facility (SAID) is moving to GW! At present, this site is under construction and the partial-wave analyses links on the left-hand side navigation bar point to the original VPI site. Once fully operational, this web page will become the main entry for the full range of services presently available through SAID. In the meantime, we welcome any suggestions you may have that will make this service more useful to the nuclear physics community (send email to cns@www.gwu.edu).

Instructions for Using the Partial-Wave Analyses

The programs accessible with the left-hand side navigation bar allow the user to obtain some of the information available through the SAID program. Contact a member of our group if you are unfamiliar with the TELNET version. If you enter choices which are unphysical, you may still get an answer (in accordance with the `garbage in, garbage out' rule). Please report unexpected garbage-out to the management. Note: These programs use HTML forms to run the SAID code. If unfamiliar with the options, run the default setup first. The output is an echo of an interactive session which would have resulted had you used the TELNET version. If the default example fails to clarify the specific task you have in mind, we can help (just send an e-mail message). All our programs expect energies given in MeV units. All of the solutions and potentials have limited ranges of validity. Some are unstable beyond their upper energy limits. Extrapolated results may not make much sense. Increments: The programs will not allow an arbitrary number of points to be generated. As a rule, stay below 60.
