Erratum: Precision mass measurements of ${}^{67}\mathrm{Fe}$ and ${}^{69,70}\mathrm{Co}$: Nuclear structure toward $N=40$ and impact on $r$-process reaction rates [Phys. Rev. C 101, 041304(R) (2020)]

Figure 1

Revised Fig. 2 of the original paper. Experimental level schemes for ${}^{67}\mathrm{Co}$ [1, 2] and ${}^{69}\mathrm{Co}$ in comparison with the shell-model calculations for the spherical (SB) and $1/2^{-}$ intruder (IB) bands in ${}^{67,69,71}\mathrm{Co}$. The $1/2^{-}$ states in Co (in blue and in red from the Rapid Communication) follow a similar trend as the $2^{+}$ and prolate $0^{+}$ [3, 4, 5, 6] intruder states in Ni (in magenta) and $7/2^{-}$ [7] states in Cu isotones (in green).

Revised Fig. 3 of the original paper. Two-neutron separation energies based on experimental values from atomic mass evaluation (AME16) [8] (in blue) and including the results from this erratum (in red). The recent ${}^{68,69}\mathrm{Co}$ measurements at LEBIT [9] (in green) introduce a kink, the same is true if only the result for ${}^{68}\mathrm{Co}$ from Ref. [9] is included, indicating that it is likely to belong to the isomer ${}^{68}\mathrm{Co}^m$. For ${}^{70}\mathrm{Co}$, AME16 is based on extrapolations (indicated with an open symbol), and our value is for the ($1^{+},2^{+}$) state.

Revised Fig. 4 of the original publication. Two-neutron shell gap parameter $D_{2n}(Z,N)=S_{2n}(Z,N)-S_{2n}(Z,N+2)$ based on AME16 [8] (in blue) and this erratum (red/magenta). Including ${}^{68,69}\mathrm{Co}$ from LEBIT [9] (in green), or only ${}^{68}\mathrm{Co}$ (in black), results in a kink at $N=40$, pointing toward an isomeric state measurement. The inset shows $D_{2n}$ for $N=40$.
