First identification of ⁵⁸Zn β-delayed proton emission

RADIOACTIVITY ^57,58Zn(β⁺), (β⁺p)[from ⁹Be(⁷⁸Kr, X), followed by separation of fragments using A1900 separator]; measured reaction products, Ep, Ip, β-delayed proton branching ratio, half-life of ⁵⁷Zn decay using the Warsaw Optical Time Projection Chamber (OTPC) with energy loss and time-of-flight method for particle identification at the NSCL-MSU facility. ⁵⁸Cu; deduced levels, J, π, β⁺p branching ratios, B(GT) for 1⁺ states. Comparison with experimental B(GT) values from ⁵⁸Ni(³He, t)⁵⁸Cu reaction, and with QRPA calculations.
