STUDIES OF EXOTIC NUCLEI AT THE RESOLUT FACILITY OF FLORIDA STATE UNIVERSITY

Abstract

The resolut facility at Florida State University’s accelerator laboratory produces beams of short-lived nuclei using the in-flight method. Its principle, performance and instrumentation is discussed. Recently, the facility was used in experiments studying the energetic location of the d_3/2–orbital in neutron-rich nuclei, which is of interest as it determines the location of the neutron drip-line in the Oxygen isotopes. Its unexpected behavior has recently been explained as a consequence of three-body forces. Here, we present the first results of these experiments regarding the spectrum of unbound d_3/2 resonances in ²⁰O.
