Lifetime measurement of the 4⁺₁ state of ⁵⁸Ni with the recoil distance method

NUCLEAR REACTIONS ⁹Be(⁷⁴Kr, ⁵⁸Ni), E=93 MeV/nucleon, [secondary ⁷⁴Kr beam from ⁹Be(⁷⁸Kr, X), E=150 MeV/nucleon]; measured reaction products, Eγ, Iγ, (⁵⁸Ni ions)γ-coin, half-life of the first 4+ state in ⁵⁸Ni by recoil distance Doppler shift method using Triple Plunger for Exotic Beams (TRIPLEX) coupled with GRETINA array and the S800 spectrograph at NSCL-MSU facility. ⁵⁸Ni; deduced level, B(E2) for the first 4+ state. Comparison with GXPF1A shell-model calculations, and with previous measurements.
