  The $^{58}$Ni$(n,\gamma)^{59}$Ni cross section was measured with a
combination of the activation technique and accelerator mass spectrometry
(AMS). The neutron activations were performed at the Karlsruhe 3.7 MV Van de
Graaff accelerator using the quasi-stellar neutron spectrum at $kT=25$ keV
produced by the $^7$Li($p,n$)$^7$Be reaction. The subsequent AMS measurements
were carried out at the 14 MV tandem accelerator of the
Maier-Leibnitz-Laboratory in Garching using the Gas-filled Analyzing Magnet
System (GAMS). Three individual samples were measured, yielding a
Maxwellian-averaged cross section at $kT=30$ keV of
$\langle\sigma\rangle_{30\text{keV}}$= 30.4 (23)$^{syst}$(9)$^{stat}$ mbarn.
This value is slightly lower than two recently published measurements using the
time-of-flight (TOF) method, but agrees within the uncertainties. Our new
results also resolve the large discrepancy between older TOF measurements and
our previous value.
