A Compton-suppressed spectrometer for studies of chaos in nuclei

One approach to studying chaos in quantum systems utilizes the statistical behavior of eigenvalues. Such analyses require data of very high quality, since both completeness and purity are essential. The design of a Compton-suppressed gamma-ray spectrometer for the purpose of establishing a nearly complete level scheme in P-30 via the Si-29(p, gamma) reaction is described. Design criteria and implementation are discussed, and early results from the system are presented.
