“…In both nuclei, however, Doppler-shift attenuation method (DSAM) lifetime experiments demonstrated that the B(E2) values in the chiral-candidate doublet bands differ considerably from each other [9][10][11]. Thus, for these nuclei the chiral scenario does not seem to hold.…”

“…Thus, for these nuclei the chiral scenario does not seem to hold. For 134 Pr, several new theoretical attempts have been made to explain the nature of the observed doublet structure [9,[12][13][14], but these have led to different conclusions. They all have concentrated on the doublet structure; however, very recently a third πh 11/2 νh −1 11/2 band was observed in 134 Pr [15] which could be a chiral partner of the previously known πh 11/2 νh −1 11/2 side band.…”

Medium- and high-spin band structure of the chiral candidate132La

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.

“…Recently, a study of the chiral doublet bands in 103 Rh has shown that the energy separation of these structures depends mainly on the core properties and, to a lesser extent, on the valence quasiparticle coupling [6]. However, the chiral interpretation in the A = 130 region has been questioned due to lifetime measurements [7,8], and it could not be confirmed by lifetime experiments in the nuclei 103 Rh and 104 Rh [9]. In this respect, it is important to understand the necessary conditions leading to the emergence of chiral geometry, one of which is the shape of the corresponding even-even core.…”

The high-spin structure of the nucleus 104 Pd was studied through the 96 Zr( 13 C,5n) reaction at incident energies of 51 and 58 MeV, using the Euroball IV γ -ray spectrometer in conjunction with the DIAMANT charged-particle array. Several new medium-and high-spin bands were revealed. The already known positive-parity yrast and the negative-parity cascades were extended up to E x ∼ 13, ∼ 11, and ∼ 9 MeV with I π = (26 + ), I π = (23 − ), and (20 − ), respectively. The deduced band structures were compared with Woods-Saxon total Routhian surface (TRS) calculations. In addition, non-yrast low-lying positive-parity bands were identified, which were assigned to soft γ -vibrational excitations.

“…At intermediate spins, there has been much discussion about chirality in odd-odd and even-Z nuclei [12][13][14][15], based on the spin axes of the unpaired proton and neutron and the rotational axis of the core. However, in this regime, in some cases there has been controversy as to the rigidity or softness of the nuclear body leading to the observed structures [16]. At the lowest spins, however, especially in the ground state itself, triaxial structures have typically been ascribed to pronounced γ softness, corresponding to a broad minimum in γ .…”

γ -ray transitions between low-spin states of the neutron-rich 84,86,88 Ge were measured by means of in-flight γ -ray spectroscopy at 270 MeV/u. Excited 6 + 1 , 4 + 1,2 , and 2 + 1,2 states of 84,86 Ge and 4 + 1 and 2 + 1,2 states of 88 Ge were observed. Furthermore, a candidate for a 3 + 1 state of 86 Ge was identified. This state plays a key role in the discussion of ground-state triaxiality of 86 Ge, along with other features of its low-energy level scheme. A new region of triaxially deformed nuclei is proposed in the Ge isotopic chain.
