A superdeformed (SD) band has been identified in a non-alpha-conjugate nucleus Cl-35. It crosses the negative-parity ground band above 11/2(-) and becomes the yrast at 15/2(-). Lifetimes of all relevant states have been measured to follow the evolution of collectivity. Enhanced B(E2), B(E1) values as well as energetics provide evidence for superdeformation and existence of parity doublet cluster structure in an odd-A nucleus in the A similar or equal to 40 region. Large-scale shell-model calculations assign (sd)(16)(pf)(3) as the origin of these states. Calculated spectroscopic factors correlate the SD states in Cl-35 to those in Ar-36.
