“…The configuration and the possible chiral nature of bands 1 and 2 have been thoroughly discussed in several papers [4,8,10,17,36]. According to those results, bands 1 and 2 both have the πh 11/2 νh 11/2 configuration; however, they do not form a chiral band structure because of the very different B(E2) values observed in the two bands.…”

Medium-and high-spin states of 132 La have been studied based on the data obtained from 100 Mo( 36 S, p3n) and 116 Cd( 23 Na, α3n) fusion-evaporation reactions using the EUROBALL and Gammasphere detector arrays, respectively. Triple-γ coincidence relations, angular correlations, and linear polarizations of the observed γ transitions have been deduced. The level scheme of 132 La has been considerably extended, and unambiguous spin and parity values have been assigned to most of the excited states. The configuration of one of the bands is πg 7/2 (h 11/2 ) 2 νh 11/2 instead of the previously thought πh 11/2 νh 11/2 ; thus its previously suggested magnetic rotational character cannot be upheld. The observed similarities between the level structures of 132 La and 134 Pr suggest the possible existence of a third πh 11/2 νh 11/2 band in 132 La that may show chiral features.

“…This restriction is one of the major drawbacks of the method because it limits its applicability to systems where triaxiality does not play an important role. However, many exciting experimental and theoretical phenomena are closely related to the triaxial degree of freedom, for instance: the presence of γ-bands in the low lying energy spectra and γ-softness, shape coexistence and shape transitions in transitional regions [13,[15][16][17][18][19][20]; the lowering of fission barriers along the triaxial path [21][22][23]; the influence of triaxial deformation in the ground state for the mass models [24,25]; triaxiality at high spin [26][27][28]; the observation of K-bands and isomeric states in the Os region [29][30][31]; or some other exotic excitation modes such as wobbling motion and chiral bands [32][33][34].…”

Triaxial angular momentum projection and configuration mixing calculations with the Gogny force

2010

We present the first implementation in the (β, γ) plane of the generator coordinate method with full triaxial angular momentum and particle number projected wave functions using the Gogny force. Technical details about the performance of the method and the convergence of the results both in the symmetry restoration and the configuration mixing parts are discussed in detail. We apply the method to the study of 24 Mg, the calculated energies of excited states as well as the transition probabilities are compared to the available experimental data showing a good overall agreement. In addition, we present the RVAMPIR approach which provides a good description of the ground and gamma bands in the absence of strong mixing.

“…Oblate bands have been observed in 131 La [3]. The most recent discovery has been the chiral doublet bands [4] and magnetic rotation bands [5]. The signature splitting and inversion are also important phenomena observed in doubly odd nuclei [6].…”

MultiparticleM1band inLa134

et al. 2007

Lifetimes of seven low-lying excited states of 134 La in the picosecond range have been determined by the recoil distance method (RDM). Lifetimes of six states, belonging to a strong M1 band and having shorter lifetimes, have been determined by the Doppler shift attenuation method (DSAM). This band with intense M1 transitions and very few weak E2 crossovers appeared to be due to magnetic rotation. However, such a possibility is ruled out because roughly constant values of B(M1) were found from the lifetime results. The semiclassical model was utilized to calculate the B(M1) values; and after being compared with the experimental results, the band was assigned the multiparticle configuration πg 7/2 ⊗ νh 11/2 (h 11/2 ) 2 , which differs from the earlier assignment of πh 11/2 ⊗ νg 7/2 (h 11/2 ) 2 .
