Title: Cross-shell excitations in ${}^{46}{Ca}$ studied with fusion reactions induced by a reaccelerated rare isotope beam

Abstract

Discovering unexplored high-spin states in neutron-rich nuclei can open up a new direction to study band structure and the associated shell structure in isospin-asymmetric many-body systems. However, experimental reach has so far been limited to neutron-deficient or stable nuclei which are preferentially produced in fusion reactions used in such studies. Here in this paper, we report the first γ-ray spectroscopy with fusion reactions using a reaccelerated rare-isotope beam of ⁴⁵K performed at the ReA3 facility of the National Superconducting Cyclotron Laboratory. Using particle and γ-ray coincidence techniques, three new higher-lying states around 6 MeV and five new γ-ray transitions were identified for ⁴⁶Ca, suggesting three independent band structures formed from different particle-hole configurations. The rotational-like band built on the 0$$^+_2$$ state is established up to the tentatively assigned 6$$^+_2$$ state. New results are compared to large-scale shell model calculations, confirming the validity of the effective interaction describing particle-hole excitations across the Z=20 and N=28 shell gaps in the vicinity of doubly-magic ⁴⁸Ca.

Yrast and near-yrast levels up to spin values in excess of I = 30h have been delineated in the doubly-magic ²⁰⁸Pb nucleus following deep-inelastic reactions involving ²⁰⁸Pb targets and, mostly, 430-MeV ⁴⁸Ca and 1440-MeV ²⁰⁸Pb beams. The level scheme was established up to an excitation energy of 16.4 MeV, based on multi-fold γ-ray coincidence relationships measured with the Gammasphere array. Below the well-known, 0.5-μs 10⁺ isomer, ten new transitions were added to earlier work. The delineation of the higher parts of the level sequence benefited from analyses involving a number of prompt- and delayed-coincidence conditions. Three new isomeric states weremore »« less

We present a high-resolution in-beam γ-ray spectroscopy study of excited states in the mirror nuclei ⁵⁵Co and ⁵⁵Ni following one-nucleon knockout from a projectile beam of ⁵⁶Ni. The newly determined partial cross sections and the γ-decay properties of excited states provide a test of state-of-the-art nuclear structure models and probe mirror symmetry in unique ways. The new experimental data are compared to large-scale shell-model calculations in the full pf space which include charge-dependent contributions. A mirror asymmetry for the partial cross sections leading to the two lowest 3/2^- states in the A = 55 mirror pair was identified as well as a significant difference in the E1 decays from the 1/2more »« less
