Abstract

The mean lifetime and

g

factor of the 2.95-MeV

6^{+}

state of

{}^{54}{Fe}

were measured to be

τ = 1.76 \pm 0.03

nsec and

| g | = 1.37 \pm 0.03

, respectively. These results are in agreement with the shell-model assignment

{({f_{\frac{7}{2}}}^{- 2})}_{π}

plus a small amount of configuration mixing which accounts for the quenching of the magnetic moment from the Schmidt limit and the enhanced

E 2

rate

B (E 2; 6^{+} \to 4^{+}) = 3.2

Weisskopf units.
