A superdeformed (SD) band has been identified in a non - alpha - conjugate nucleus 35Cl. 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 as well as formation of a cluster structure. Energetics as well as enhanced B(E2) and B(E1) values provide evidences for superdeformation as well as its relation to parity doublet cluster structure for the first time in A ≈ 40 region. Large scale shell model calculations assign (sd)16(pf)3 as the origin of these states. Calculated spectroscopic factors also correlate the SD states in 35Cl to those in 36Ar.
