${{\mathit N}}(\sim{}$3000 Region) Partial-Wave Analyses

We list here miscellaneous high-mass candidates for isospin-${}^{}1/2{}^{}$ resonances found in partial-wave analyses. Our 1982 edition had an ${{\mathit N}{(3245)}}$, an ${{\mathit N}{(3690)}}$, and an ${{\mathit N}{(3755)}}$, each a narrow peak seen in a production experiment. Since nothing has been heard from them since the 1960's, we declare them to be dead. There was also an ${{\mathit N}{(3030)}}$, deduced from total cross-section and 180$^\circ{}$ elastic cross-section measurements; it is the KOCH 1980 ${\mathit L}_{\mathrm 1,15}$ state below.
