Possible “umbrella”-like antimagnetic rotation mode in odd- A Pd101,103 and even-even Pd102

Theoretical investigation of the antimagnetic rotation in 104Pd *

“…Due to the fact that the MOIs of the gsb in 104 Pd are reproduced very well by the present PNC-CSM calculation, the configuration of this AMR band should be reasonable. Later on, the configuration obtained by the present calculation will be compared with previous works [12,26]. Usually, typical AMR has weak E2 transitions and large J (2) /B(E2) ratios, which reflect the nearly spherical or weakly deformed core.…”

“…The data show that the possible AMR band in 104 Pd is the yrast band after the backbending [12]. Using the semiclassical particle rotor model, its configuration was assumed to be πg − ] in a recent investigation using TAC-CDFT [26]. Therefore, to clarify its configuration, in the following investigation, adiabatic calculations for the gsb in 104 Pd will be performed and the configuration for this AMR band can be obtained automatically after neutron level crossings.…”

“…AMR has been investigated theoretically mainly by the semi-classical particle rotor model [19], and the tilted axis cranking (TAC) model [20][21][22]. Especially, many investigations have been performed within the framework of microscopic-macroscopic model [4,6,16], pairing plus quadrupole model [2,15], and the covariant density functional theory (CDFT) [23][24][25][26] based on the TAC model (for reviews please see Refs. [27,28]).…”

“…Using the semiclassical particle rotor model, its configuration was assumed to be πg −2 9/2 ⊗ ν[h 2 11/2 , (g 7/2 , d 5/2 ) 2 ] [12]. However, this band was assigned a different configuration as πg −4 9/2 ⊗ ν[h 2 11/2 , (g 7/2 , d 5/2 ) 6 ] in a recent investigation using TAC-CDFT [26] with the point coupling effective interaction PC-PK1 [29]. Note that these two configurations are all written with respect to the 100 Sn core.…”

Possible antimagnetic rotation bands in $^{100}$Pd: a particle-number conserving investigation

“…From the theoretical aspect, AMR has been investigated mainly by the semi-classical particle rotor model [18], and the tilted axis cranking (TAC) model [19][20][21][22][23]. Based on the TAC model, many investigations have been performed within the framework of pairing plus quadrupole model [2,13], microscopic-macroscopic model [4,6,24], and the covariant density functional theory [25][26][27][28][29][30] with the point coupling effective interaction PC-PK1 [31].…”
