Abstract.

In this paper,we report our measurements of back-angle oxygen and carbon particle yields from 16O +89Y,12C +93Nb reactions forming the same compound nucleus 105 Ag at the same excitation energy and spin distribution. We find anomalously large oxygen yield and entrance channel dependence at high excitation energies from 16 O + 89 Y reaction implying formation of a dinuclear orbiting complex. Possible connection between nuclear orbiting and fast fission is also discussed.

Keywords. Entrance channel dependence; orbiting.
