Proton spectroscopy of ⁴⁸Ni, ⁴⁶Fe, and ⁴⁴Cr

RADIOACTIVITY ⁴⁸Ni(2p); ⁴⁴Cr, ⁴⁶Fe(β⁺p); ⁴⁶Fe(β⁺2p); [⁴⁴Cr, ⁴⁶Fe, ⁴⁸Ni activities from Ni(⁵⁸Ni, X), E=160 MeV/nucleon]; measured Ep, Ip, half-lives of ground states of ⁴⁴Cr, ⁴⁶Fe, ⁴⁸Ni, proton branching ratios using an optical time projection chamber (OPTC). Reconstruction of the four 2p-decay events from decay of ⁴⁸Ni; deduced Q(2p). Comparison previous experimental results.

NUCLEAR REACTIONS Ni(⁵⁸Ni, X)⁴⁴Cr/⁴⁶Fe/⁴⁸Ni, E=160 MeV/nucleon; measured fragment spectra, time-of-flight, energy loss and production σ using A1900 separator and standard acquisition system at NSCL-MSU facility. LISE++ analysis. Comparison with EPAX-3 and EPAX-2.1 parametrizations.
