In-beam ..gamma..-ray spectroscopy in concert with both massive transfer and fusion reactions has been used to study high-spin states in the relatively neutron-rich /sup 102/Ru and adjacent mass 100 transitional nuclei. Backbending in /sup 102/Ru is shown to result from the alignment of a pair of h/sub 11/2/ neutrons. Blocking arguments and cranked shell model calculations support this. Alignment of a pair of h/sub 11/2/ neutrons in the g/sub 9/2/ proton band of /sup 103/Rh changes the signature splitting and B(M1)/B(E2) ratios.
