High spin states in ${}^{74}{Br}$

States of

{}^{74}{Br}

excited through the

{}^{60}{Ni} ({}^{16}O, n p)

reaction at

E = 40 to 55

MeV were studied. From the excitation function,

γ

-ray angular distribution,

γ - γ

coincidences, and decay measurements three groups of

γ

rays depopulating states with probable spin values ranging up to

I = (11)

were found. A half-life of 49.5 min and

I = (4)

for the high spin isomeric state at

E \approx 200

keV were determined at variance with previous values of 41.5 min and

I = (4^{-})

. The group of

γ

rays feeding the

I = (4)

isomer shows similarities with a recently reported band built on a

4^{+}

isomer in both

{}^{76}{Br}

and

{}^{78}{Br}

. The interpretation of these states as members of the

\tilde{π} g_{\frac{9}{2}} \otimes \tilde{ν} g_{\frac{9}{2}}

structure is discussed.
