Highly excited alpha-cluster states in

The elastic-scattering reaction 30Si + $\alpha$ was studied using the Thick Target Inverse Kinematics technique. Data were taken at a 30Si beam energy of 150MeV in a reaction chamber filled with 4He gas, corresponding to the excitation region of 12-24MeV in 34S . The data were treated in the framework of a simplified R -matrix approach, and energies, widths and spin assignments were obtained for 111 resonances in an approximative manner. The structure is discussed within the concept of $\alpha$ -cluster structure in the quasi-continuum of 34S and is compared to recent data for 32S
