Description
By bombarding a 232Th target with a 36S beam we aim to populate, via multi-nucleon transfer
and deep-inelastic reactions, yrast and yrare states in neutron-rich isotopes in order to explore the
new region of deformation and the doorway states that give rise to the island of inversion (IoI)
at N = 20. The coupling of the AGATA array to the Prisma spectrometer will allow to map the
boundaries of the IoI at N = 20 and its possible extension towards N = 28. It will be possible to
extend up to 6 units of angular momentum above the g.s.. Moreover, it will be possible to cover
some notable gaps left from previous experiments such as 35P, to be extended from 7/2− up to
13/2− and 34Si for which we will observe for the first time the 4+ and the 6+ states. With this
experiment we will investigate in this exotic region the shape coexistence and the robustness of the
quadrupole collectivity with increasing excitation energy and angular momentum.
