摘要：

A group of decay sequences in Br-77,Br-79,Br-81, Kr-79, Rb-79,Rb-81,Rb-83,Rb-85, Zr-83, and Y-83 With many common characteristics are compared. All of these sequences start in the region of the first band crossing, have strong Delta I = 1 decays with little or no Delta I = 2 branches, no signature splitting, and negative parity. The first state has spin 13/2h or greater. Deformed shell model calculations suggest a pi g(9/2) x nu(fP) x nu g(9/2) configuration for the Br isotopes. There are a number of similarities with the oblate Delta I = I bands in the A approximate to 130 region and with ''shears bands'' in the Pb region.
