“…As observed in [2], the distribution of the 0 + transfer intensity with excitation energy in 168 Er differs from that of the other eight nuclei from the rare-earth region. It is also different from that observed in its neighbour 166 Er [7]. The spdf-IBM calculations describe reasonably well the strong increase of this transfer intensity around 1.8 MeV in 166 Er, while they fail to describe the increase around 2.8-3.0 MeV from 168 Er [7].…”

“…The two-neutron transfer intensities for the 0 + states was also calculated for both these nuclei; while for 166 Er it is described reasonably well, the experimental features for 168 Er, consisting of a strong increase of the cumulative 0 + transfer strength around 2.7 MeV is not well described (see Fig. 9 of [7]). Other transfer intensities were not calculated, because realistic 2n-transfer operators within this model contain a large number of parameters for each transferred L-value.…”

“…The parameters of these calculations are given in Ref. [7], where predictions of such calculations were compared with experimental data for both 166 Er and 168 Er. The two-neutron transfer intensities for the 0 + states was also calculated for both these nuclei; while for 166 Er it is described reasonably well, the experimental features for 168 Er, consisting of a strong increase of the cumulative 0 + transfer strength around 2.7 MeV is not well described (see Fig.…”

“…These may be related to the presence of multistep excitations, which can be taken into account by performing CC calculations with CHUCK3. Such an approach was demonstrated as very useful for the 230 Th nucleus [4], 228 Th [5], 158 Gd [6], as well as for the 166 Er nucleui [7].…”

“…When performed with high-energy resolution, one may identify a large number of excited states with low to medium spins in nuclei, and even uniquely determine their spin and parity. Many such studies were performed at the MLL (Maier-Leibnitz Laboratory of LMU Munich and TU Munich) MP tandem accelerator using a Q3D magnetic spectrograph and a good position-sensitive focal plane detector [1][2][3][4][5][6][7]. A campaign of (p,t) reaction experiments was initiated in 2005 with a study of eight nuclei in the rare earth region.…”

More than 200 states up to 4.1 MeV excitation have been populated in 168 Er with the 170 Er(p,t) reaction at 25 MeV incident energy. About 80 of these states, with 0 + and 2 + assignments, were reported in a previous publication (Phys. Rev C 73, 064309(2006)). The present work considerably enriches the knowledge of this nucleus. A multistep coupled-channel analysis of the angular distributions is now presented for all the states observed in this experiment. Spin and parity values between 0 + and 7 − are newly assigned for more than 100 states. For the states already reported in the ENSDF database with J π values there a good ageement with our values. The 168 Er nucleus remains one of the best experimentally known nuclei for states with low and medium spins below 4 MeV excitation energy, representing a challenge for future structure microscopic model calculations aiming to disentangle the contributions of different excitation degrees of freedom.
