Detailed $$gamma$$-ray spectroscopy of the exotic neon isotope $$^{28}$$Ne has been performed using the one-neutron removal reaction from $$^{29}$$Ne. Based on an analysis of parallel momentum distributions, a level scheme with spin-parity assignments has been constructed for $$^{28}$$Ne and the negative-parity states are identified for the first time. The measured partial cross sections and momentum distributions reveal a significant intruder p-wave strength providing evidence of the breakdown of the N = 20 and N = 28 shell gaps. Only a weak, possible f-wave strength was observed to bound final states. Large-scale shell-model calculations with different effective interactions do not reproduce the large p-wave and small f-wave strength observed experimentally, indicating an ongoing challenge for a complete theoretical description of the transition into the island of inversion along the Ne isotopic chain.

The hfs separation $$Deltanu$$ of $$^{126}$$Cs($$T$$$$_{1/2} = 1.63$$ m) in the 6s $$^2$$S$$_{1/2}$$ ground state was obtained in a precision measurement near zero magnetic field by means of atomic beam magnetic resonance with laser optical pumping on-line with the CERN-PSB-ISOLDE mass separator. The result, $$Deltanu = 3629.514(0.001)$$ MHz, corrects significantly a previous published value from a high-field experiment. With our result, the precision of the nuclear magnetic moment, $$mu(^{126}$$Cs)$$sim 0.776 mu_N$$, is now limited by the influence of extended nuclear structure on the hfs (the Bohr-Weisskopf effect).
