“…Highly deformed bands have been observed at medium to very high spin in several Nd nuclei [14,[20][21][22][23][24]. Superdeformed bands have been observed in Ce nuclei [38,[50][51][52][53][54][55][56][57][58][59][60][61][62][63].…”

The level structure of 136 Nd has been investigated using the 100 Mo(40 Ar, 4n) reaction and the JUROGAM II+RITU+GREAT setup. The level scheme has been extended significantly. Many new bands have been identified both at low and high spin, among which are five nearly degenerate bands interpreted as chiral partners. Excitation energies, spins, and parities of the previously known bands are revised and firmly established, and some previously known bands have been revised. Configurations are assigned to the observed bands based on cranked Nilsson-Strutinsky calculations. The band structure of 136 Nd is now clarified and the various types of single-particle and collective excitations are well understood.

“…The deformation of the new bands in 122 Te probably lies in this range as well. For comparison, the superdeformed band in 132 Ce [34] with ε 2 0.4 is included in Fig. 9; its moment of inertia is appreciably larger.…”

High-spin states in 122 Te were populated in the reaction 82 Se(48 Ca, α4n) 122 Te at a beam energy of 200 MeV and γ-ray coincidences were measured with the Gammasphere spectrometer. The previously known level scheme was extended to considerably higher spin. Maximally aligned states and several high-energy transitions feeding into some of these levels were observed. In addition, seven collective high-spin bands were discovered for the first time in this nucleus. The experimental results are compared with cranked Nilsson-Strutinsky model calculations and possible configuration assignments to the new high-spin structures are discussed.

“…In addition, there is also a theoretical reason, related to the presence of holes in the π g 9/2 orbital in the assigned configurations, which is possible at large deformation, like in the SD bands of the A = 150 mass region [1]. Fourteen SD bands have been identified in the Ce nuclei from 129 Ce to 134 Ce [2][3][4][5][6][7][8][9][10]. None of these bands was linked to low-lying states.…”

Three new highly-deformed (HD) bands are identified in 136 Nd and the highly deformed band of 137 Nd is extended at higher spin by four transitions, revealing a band crossing associated with the occupation of the second νi 13/2 intruder orbital. Extended cranked Nilsson-Strutinsky calculations are performed for all HD bands observed in 134 Nd, 136 Nd, and 137 Nd, achieving for the first time a consistent interpretation of all HD bands in the Nd nuclei. The new interpretation has significant consequences, like the change of parity of the yrast HD bands of 134 Nd and 136 Nd, and the involvement of two negative-parity neutron intruder orbitals in the configurations of most HD bands. The present experimental results and their theoretical interpretation represent an important step forward in the understanding of the second-minimum excitations in the Nd nuclei.
