“…Indeed different manifestation of the shears mechanism with single shear structure have been found in mass regions viz. A ∼ 80, 100, 140 and 190 [18][19][20][21][22][23][24][25][26][27]. Since both these two types of quantized rotation are the consequence of the shear mechanism, it is expected to observe both of them in the mentioned mass regions.…”

“…Since both these two types of quantized rotation are the consequence of the shear mechanism, it is expected to observe both of them in the mentioned mass regions. However, till day, simultaneous occurrence of these two phenomena have been observed only in mass ∼ 100 region where firm experimental evidence of antimagnetic rotation has been reported in several Cd [9][10][11][12][13][14] isotopes and in the 104 Pd nucleus [15] along with the observation of MR bands [22,23]. These bands have been interpreted in the framework of simple geometric model [14,28,29] and as well as the fully self-consistent microscopic tilted axis cranking method based on covariant density functional theory [30].…”

“…The quoted errors in the lifetimes do not include the systematic error due to the uncertainty in the stopping power which can be as large as 15%. The level lifetimes have been evaluated in the present analysis by considering the side feeding from both observed as well as unobserved transitions to the level under consideration [23]. Thus the lifetime for the 47/2 + state has been evaluated by including the 969 keV transition [35] in the feeding history parallel to the 866.5 keV transition.…”

Antimagnetic rotation and sudden change of electric quadrupole transition strength in 143 Eu

Lifetimes of the states in the quadrupole structure in 143 Eu have been measured using the Doppler shift attenuation method and the parity of the states in the sequence has been firmly identified from polarization measurements using the Indian National Gamma Array. The decreasing trends of the deduced quadrupole transition strength B(E2) with spin, along with increasing J (2) /B(E2) values before the band crossing, conclusively establish the origin of these states as arising from antimagnetic rotation. The abrupt increase in the B(E2) values after the band crossing in the quadrupole band, a novel feature observed in the present experiment, may possibly indicate the crossing of different shears configurations resulting in the re-opening of a shears structure. The results are reproduced well by numerical calculations within the framework of a semi-classical geometric model.

“…Magnetic rotational or antimagnetic bands have been identified in Rh, Ag, Cd, In, Sn, and Sb isotopes in the A ≈ 110 mass region where the nuclei involve coupling of one or more proton holes in the high-g 9/2 orbitals with neutrons in the low-g 7/2 , d 5/2 , and h 11/2 orbitals. Magnetic rotational bands are also expected in 107 Ag, in addition to 103−106 Ag [3][4][5][6][7] and 109 Ag [8] in Ag isotopes. The level scheme of 107 Ag has been reported previously [9][10][11].…”

The excited states in 107 Ag were populated through the heavy-ion fusion evaporation reaction 100 Mo ( 11 B, 4n) 107 Ag at a beam energy of 46 MeV. Lifetimes of high-spin states in 107 Ag have been measured through the Doppler shift attenuation method. The deduced B(M1) values, gradually decreasing with increasing spin, clearly demonstrate that both the yrast positive-parity band and the yrast negative-parity band in 107 Ag are magnetic rotation bands. Furthermore, experimental deduced B(M1) values for the yrast positive-parity band are compared with the predictions of the particle rotor model. The approximate agreement between theoretical calculations and experimental results further confirms the mechanism of magnetic rotation for the yrast positive-parity band. In addition, a systematic investigation shows the evolution of the magnetic rotation mechanism in the A ≈ 110 mass region.

“…Traditional rotational band in deformed nuclei is characterized by strong electric quadrupole (E2) transitions [1], while magnetic-rotational band by the magnetic dipole (M1) transitions and the multi-quasi-particle configurations [2]. The angular momentum vector of the valence proton particles is perpendicular to that resulting from the valence neutron holes at the band head in Pb isotopes [3].…”

g-Factors of magnetic–rotational states in 85Zr

et al. 2007

The g-factors of the magnetic-rotational intra-band states in 85 Zr have been measured by the TMF-IMPAD method for the first time. The configuration π g 9/2 2 8 ⊗ ν f 7/2 is established for the band. The measured g-factors are in good agreement with those calculated by the semi-classical model. The decrease of both g-factors and shears angles along the band shows that the total angular momentum is generated by the sheras effect of a step-by-step alignment of the valence protons and neutrons. The rapid neutron alignment leads to a decrease of g-factors along the band. The shears angle of the band-head is great than 90 • , which implies that the spin-dependent interaction as well as the residul interaction might be involved in the shears mechanism in 85 Zr.
