Enhanced deuterium-tritium fusion cross sections in the presence of strong electromagnetic fields

Multiple chiral bands in $$^{137}$$Nd

“…The excitation energies of bands D2 and D3, as well as those of the bands D5 and D6, are very similar. These four bands correspond, one to one, to the bands identified in 135 Nd [11]. However, the agreement between the theoretical curves and the data points is poor at lower spins, in particular for band D2, due to strong mixing with many other states present in the same energy region, not all shown in Fig.…”

“…A sudden increase of the single-particle alignment of 2h is observed in both bands D4 and D5 at slightly different rotational frequencies, which was investigated by calculating different possible additional aligned quasiparticles. A similar crossing can exist in band D6, but may be sharper and The configuration νh −1 11/2 ⊗π [h 1 11/2 (d 5/2 , g 7/2 ) −1 ] assigned to band D2, is similar to that assigned to the corresponding bands of 135 Nd [11] and 133 Ce [9]. The alignment of the new band D3, larger by 2h than that of band D2, is different from the nearly identical alignments of the corresponding positiveparity bands in 135 Nd and 133 Ce.…”

“…Bands built on configurations involving three-, four-and six-quasiparticles have been observed in this mass region ( 133 La [8], 133 Ce [9], 135 Nd [10,11], 136 Nd [12,13] and 138 Nd [14][15][16]). The present work is devoted to the study of chirality in 137 Nd, the odd-even neighbor of 135 Nd and 136 Nd, in which multiple chiral doublet (Mχ D) [17] bands have been recently identified [11][12][13]. Prior to this work, the 137 Nd nucleus has been investigated both experimentally [18,19,[22][23][24] and theoretically [25].…”

“…7, we observe large values of i x for all bands D2-D5, with a difference of 2h between D2 and D3, as well as between D5 and D6, due to either different Fermi levels for protons and neutrons implying the occupation of different Nilsson orbitals, and/or different moments of inertia induced by the active quasiparticles. However, this 2h difference between the doublet bands can be interpreted as possibly resulting from the presence of chi- ral vibration, like in the case of the 135 Nd nucleus (see e. g. [10,11]). The ≈ 7h alignment difference between band D2 and band D1 based the one-quasiparticle νh −1 11/2 configuration, clearly indicates a 3-quasiparticle configuration for band D2, with two more nucleons placed in the opposite-parity proton orbitals h 11/2 and (d 5/2 , g 7/2 ), leading to the νh −1…”

“…The present experimental results are obtained from the same data set from which were obtained the results of Refs. [11,12,22,30,31].…”
