Collective properties of odd-Z /sup 115,117/I and /sup 121,123/Sb nuclei have been investigated via /sup 106/Cd(/sup 12/C,p2n)/sup 115/I, /sup 106/Cd(/sup 14/N,2pn)/sup 117/I, /sup 112/Sn(/sup 12/C,..cap alpha..p2n)/sup 117/I, and /sup 120,122/Sn(/sup 7/Li,..cap alpha..2n) /sup 121,123/Sb reactions, using in-beam ..gamma.. excitation, ..gamma..-..gamma.. coincidence, ..gamma..-W(theta) and pulsed-beam-..gamma.. measurements. The two collective features common to the Z>50 transition region were observed; the first, the occurrence of ..delta..J = 1 bands built on low-lying (9/2)/sup +/ states, was found in all four nuclei, and the second, ..delta..J = 2 bands built on (11/2)/sup -/ states, was seen in /sup 115,117/I. The (9/2)/sup +/ and (11/2)/sup -/ band heads involve a 1g/sub 9/2/ proton hole and a 1h/sub 11/2/ quasiproton, respectively. The systematics of these band structures in the Z>50 transition region, which have been extended in this study, are presented and discussed in terms of collective interpretations.
