Erratum to “ g -factor and quadrupole moment of the 212− isomeric state in 131 La: Signature for a weakly-deformed magnetic rotational band head” [Phys. Lett. B 765 (2017) 317–322]

The g -factor and the static quadrupole moment of a magnetic rotational band head 212− at 2121 keV in 131 La have been determined by means of the time-differential perturbed angular distribution technique. The measured value of the g -factor, +1.060(4) , is in agreement with the theoretical value for a three quasi-proton, π3{112−[505]⊗52+[422]⊗52+[413]} Nilsson configuration assignment. The observed spectroscopic quadrupole moment ratio, Qs(212−,131La)Qs(192−,137La)=0.457(4) , supports the collective oblate shape (γ∼−60°) with quadrupole deformation β2&lt;0.07 . The half-life of the 212− state, 37.2(1) ns, is re-measured with better accuracy.
