Abstract

An isomeric state in

{}^{52}{Fe}

has been located at

E_{x} = 6.83 \pm 0.25

MeV with the reaction

{}^{40}{Ca} ({}^{14}N, p n) {}^{52}{Fe}

. The state decays by positron emission to the (

11^{+}

) 3.837-MeV state of

{}^{52}{Mn}

with

T_{\frac{1}{2}} = 56 \pm 8

sec. The probable spin and parity of the isomer is

12^{+}

.
