Підтримка:The author would like to acknowledge
I. I. Strakovsky for valuable correspondence on the topic
and R. A. Armdt for kindly sending the data on the
residue before publication. The extremely value of information
system SAID (George Washington University,
USA) has to be underlined, too.
In the framework of a resonance model the D(1232) pole characteristics are determined from the data of several pN elastic scattering analyses on the Р₃₃.phase shift. For the residue an approximated analytical formula is obtained is obtained that was used to analyze the connection between the background and pole parameters.
