Highly excited alpha-cluster states in S-32 studied with the thick-target inverse kinematics method Academic Article uri icon

abstract

  • Excitation functions of elastic 28Si + scattering were measured employing the relatively new thick-target inverse kinematics technique, confirming the usefulness of the method. Data were taken at a 28Si beam energy of 150MeV in a reaction chamber filled with 4He gas, corresponding to the excitation region of 10-24MeV in 32S. Results are compared to earlier studies, in order to validate the method and explore its limitations. The data were treated in the framework of a simplified R -matrix approach. Energies, widths and spin assignments were obtained for 129 resonances in this mid-shell nucleus. The structure is discussed within the concept of -cluster structure in the quasi-continuum of 32S. 2010 SIF, Springer-Verlag Berlin Heidelberg.
