The high spin structure of ^129,131Cs are investigated in-beam using fusion evaporation reactions.  15 bands in ¹³¹Cs and 9 bands in ¹²⁹Cs, both of positive parity and negative parity, are established.  Particle configurations to various bands are assigned using PHF and TAC model calculations.  Degenerate doublet bands in the Cs nuclei are also observed.

The high spin structure of ¹⁰⁷In and ⁹⁹Pd are also investigated.  7 bands in ¹⁰⁷In and 6 bands in ⁹⁹Pd are established.  Particle configurations are assigned using deformed HF and angular momentum projection techniques in ¹⁰⁷In, while data analysis and model calculations are going on for the ⁹⁹Pd. 

The details of structure of these nuclei will be discussed.
