Beta-delayed proton decay of 57Zn has been investigated at the GSI on-line isotope separator. The studied 57Zn nuclei were produced in fusion evaporation reactions by using a150 MeV 32S beam on a 28Si target. Beta-delayedprotonsweremeasuredbyacharged-particle
telescope detector.The observed decay pattern was used to construct the level scheme of 57Cu and to extract the beta feeding distribution. The experimental results are compared with shell-model calculations.
