In-beam $\gamma$ -ray spectroscopy of Mg35 via knockout reactions at intermediate energies

The isotope Mg-35 was spectroscopically studied via nucleon-removal reactions from Mg-36 and Al-37 secondary beams at intermediate energies. The experiment's aim was to clarify the level structure of this nucleus located in between the N = 20 and 28 shell quenchings. De-excitation gamma-ray energies, exclusive cross sections, and parallel momentum of outgoing Mg-35 for several final states were measured and compared to structure calculations in the shell model and antisymmetrized molecular dynamics framework and the eikonal reaction calculation, further developing the level scheme of Mg-35. It was found that a large fraction of the one-neutron knockout reaction goes into unbound states of Mg-35, which may explain missing f-wave strength.
