Abstract: In the experiments at the SPHINX facility in the 70 GeV proton beam of the IHEP accelerator the diffractive production reactionsp+N→[Σ(1385)<superscript>0</superscript>K<superscript>+</superscript>] +N andp+N→[Σ(1385)<superscript>0</superscript>K<superscript>+</superscript>]+N+ (neutral particles) were studied. In the effective mass spectra of the [Σ(1385)<superscript>0</superscript>K<superscript>+</superscript>] system in these processes there were no signals from the anomalously narrow baryon stateN<subscript>ϕ</subscript> (1960) which had been observed earlier in the measurement at the BIS-2 setup.
