One-proton and one-neutron knockout reactions from $N=Z=28$ ${}^{56}$Ni to the $A=55$ mirror pair ${}^{55}$Co and ${}^{55}$Ni

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

We present a high-resolution in-beam $\gamma$-ray spectroscopy study of excited states in the mirror nuclei ${}^{55}$Co and ${}^{55}$Ni following one-nucleon knockout from a projectile beam…
