Resumen
States of 74Br excited through the 60Ni(16O
*/>) reaction at E = 40 to 55 MeV were studied. From the excitation function
x-ray angular distribution
y-y coincidences
and decay measurements three groups of y rays depopulating states with probable spin values ranging up to / = (11) were found. A half-life of 49.5 min and I = (4) for the high spin isomeric state at E ~ 200 keV were determined at variance with previous values of 41.5 min and I = (4~). The group of y rays feeding the / = (4) isomer shows similarities with a recently reported band built on a 4+ isomer in both 76Br and 78Br. The interpretation of these states as members of the 7rg9/2 ® vg9/2 structure is discussed.
