Rotation in near and beyond proton and neutron drip line nuclei

Two new mechanisms active in rotating nuclei located in the vicinity of neutron and proton drip lines have been discovered [1,2]. Strong Coriolis interaction acting on high-j orbitals transforms particle-unbound (resonance) nucleonic configurations into particle-bound ones with increasing angular momentum. The point of the transition manifests the birth of particle-bound rotational bands. Alternative possibility of the transition from particle-bound to resonance rotational band (the death of particle-bound rotational bands) with increasing spin also exists but it is less frequent in the calculations. The birth of particle-bound rotational bands provides a mechanism for the extension of nuclear landscape beyond its boundaries in non-rotating nuclei. The mapping of nuclear landscape boundaries in rotating nuclei and systematic search of best candidates for experimental observation of these two phenomena are in progress [3]. Their results will be presented. [1] A.V.Afanasjev, N.Itagaki and D.Ray, Phys.Lett. B 794 (2019) 7. [2] A.V.Afanasjev, S.E.Agbemava and A.Taninah, Acta Physica Polonica, in press [3] S. Teeti, A.
