Abstract

An analysis of

p - p

interactions at 6 BeV/c indicates the presence of a

T = \frac{3}{2}

nucleon resonance with mass near 2.0

{B e V / c}^{2}

, with decay modes

Y^{* + +} (1385) K^{+}

,

N^{* + +} (1236) ρ^{0}

, and

N^{* + +} (1236) π^{+} π^{-}

. A peripheral production model for the reaction

pp \to n N^{* + +} (1950)

gives excellent agreement with the data, with a cross section for

N^{* + +} (1950)

production and subsequent decay into

Y^{* +} K^{+}

of 13±3 μb.
