Isoscalar Giant Resonance Strengths in ${}^{32}$S and possible excitations of superdeformed and ${}^{28}$Si + $\alpha$ cluster bandheads

Isoscalar giant resonances and low spin states in ${}^{32}$S have been measured with inelastic $\alpha$ scattering at extremely forward angles including zero degrees at E${}_{\alpha }$ = 386 MeV. By applying the multipole decomposition analysis, various excited states are classified according to their spin and parities (J${}^{\pi }$), and are discussed in relation to the super deformed and ${}^{28}$Si + $\alpha$ cluster bands.
