Spectroscopic strengths and 1p1h contributions to the low-lying dipole response in <sup>50</sup>Ti

ORAL

Abstract


As part of an ongoing experimental program in the A=50 mass region at Florida State University’s John D. Fox Superconducting Linear Accelerator Laboratory, we have performed high-resolution (d,p) measurements on 50Ti using the Super-Enge Split-Pole Spectrograph (SE-SPS). Angular distributions have been used to extract spectroscopic factors and map the neutron single-particle strength up to the neutron separation threshold. These results are compared to predictions from energy density functional (EDF) theory coupled with the quasiparticle-phonon model (QPM). By incorporating particle-γ coincidences in (d,pγ) measurements with the newly commissioned CeBrA γ-ray array in conjunction with the SE-SPS, we are also able to aid in spin-parity assignments of observed states in 50Ti and assess the purity of the target composition. In this talk, I will present a comprehensive spectroscopic study of 50Ti and discuss key observations of the neutron single-particle strength up to the neutron separation energy, with emphasis on the low-lying dipole response in the A=50 mass region.
