Multiple antimagnetic rotation bands in odd- Cd
Physical Review C—Nuclear Physics, 2013•APS
Lifetimes of the excited states of a pair of positive-parity Δ I= 2 bands of 107 Cd have been
measured by using the Doppler-shift attenuation method. The obtained B (E 2) transition
rates significantly decrease with increasing spin, a behavior typical of antimagnetic rotation
(AMR). The observed results, interpreted by the semiclassical model (SCM) calculations,
confirm these bands to be AMR bands resulting from the coupling of a pair of high-Ω g 9/2
proton holes to aligned g 7/2 (h 11/2) 2 neutron particles. This is the first evidence for two …

Lifetimes of the excited states of a pair of positive-parity bands of Cd have been measured by using the Doppler-shift attenuation method. The obtained transition rates significantly decrease with increasing spin, a behavior typical of antimagnetic rotation (AMR). The observed results, interpreted by the semiclassical model (SCM) calculations, confirm these bands to be AMR bands resulting from the coupling of a pair of high- proton holes to aligned neutron particles. This is the first evidence for two AMR bands in a single nucleus.
