Experimental identification of the $T=1$, $J^{\pi }=6^{+}$ state of ${}^{54}$Co and isospin symmetry in $A=54$ studied via one-nucleon knockout reactions

M. Spieker, D. Weisshaar, A. Gade +15

New experimental data obtained from $\gamma$-ray tagged one-neutron and one-proton knockout from ${}^{55}$Co is presented. A candidate for the sought-after $T=1,T_z=0,J^{\pi }=6^{+}$ state…
