The Institute of Nuclear and Particle Physics (INPP) presents Andrea Richard, of Ohio University, “33Mg from a Simple Perspective” on Tuesday, Feb. 21, at at 4 p.m. in Edwards Accelerator Lab, Roger W. Finlay Conference Room.
Abstract: The “Island of Inversion” at N≈20 for the neon, sodium, and magnesium isotopes has long been an area of interest both experimentally and theoretically due to the presence of particle-hole excitations that lead to deformed ground states. However, the presence of rotational band structures, which are fingerprints of deformed shapes, have only recently been observed. Results from a measurement of the low-lying level structure in 33Mg populated via a two-stage projectile fragmentation reaction and observed using GRETINA will be presented. I will show that the experimental level energies, magnetic moment, and γ-ray intensities show good agreement with leading order calculations in the strong-coupling limit of the rotational model.
