110. $\beta$-decay spectroscopy activities at ALTO

Mathieu Lebois (University Paris-Saclay and IJCLab, France)

2/1/23, 9:25 AM

A little more than ten years ago, the very first electron beam was produced with the ALTO electron LINAC. 50 MeV and 10 µA later, the induced photofission process allow the production of exotic neutron rich isotopes. Based on the ISOL technique, ALTO has shown its capability to produce radioactive ion beams in the $^{78}$Ni mass region. Since then, the Orsay team working with the facility...

111. Lifetime measurements of neutron-deficient odd-A W and Os nuclei

Tuomas Grahn (Jyväskylä University, Finland)

113. Underlying mechanism responsible for even-parity ground state and one-neutron halo of 11Be (remote)

Wen Hui Long (Lanzhou University, China)

2/1/23, 10:40 AM

Using the axially deformed relativistic Hartree-Fock-Bogoliubov (D-RHFB) model, we explore the mechanism that triggers the novelties in $^{11}$Be, i.e., the parity inversion and one-neutron halo which are well reproduced by the RHF Lagrangian PKA1. Following the evolution from spherical to large prolate shapes, it is illustrated that the evidently enhanced $\pi$-pseudo-vector ($\pi$-PV) and...
