Description
The solenoidal-spectrometer technique was pioneered at Argonne just over 15 years ago with the HELIOS spectrometer. Its success has been emulated in Europe at CERN’s HIE-ISOLDE facility with the ISOLDE Solenoidal Spectrometer and at DOE’s Facility for Rare Isotope Beams with SOLARIS. Solenoidal spectrometers are highly versatile tools, perhaps more so than originally imagined, for studying direct reactions in inverse kinematics (mainly with radioactive ion beams) with good resolution. From the solenoidal spectrometer programs at ATLAS, CERN, and FRIB, key insights have emerged: the behavior of single-particle energies in weakly bound nuclei suggests a seemingly ubiquitous way nuclear structure evolves towards the limits of stability. I will present physics highlights from recent measurements that reflect this.
