Abstract

The

N^{*} (1730)

with a mass of 1730 ± 15 MeV and a width of 130± 30 MeV is produced in the reaction

π^{-} p \to π^{-} N^{*} {(1730)}^{+}

at

6 \frac{GeV}{c}

. The principal decay mode of this

N^{*}

is

N π π

and not

Δ π

. The

N π

decay rate is found to be much smaller, and the

Λ K

decay rate is found to be much larger than the accepted rates for the well-known

N_{\frac{1}{2}}^{*} (1680)

states (

D_{\frac{5}{2}}

and

F_{\frac{5}{2}}

), thus establishing that the object that we observe is not the

N_{\frac{1}{2}}^{*} (1680)

.
