The excited states of 201At were studied and an isomeric 29/2
+ state [T1/2 = 3.39(9) μs] was identified by
using a fusion-evaporation reaction, a gas-filled recoil separator, and recoil gating techniques. The 29/2
+ state is
suggested to originate from the π(h9/2) ⊗ |200Po;11− configuration, and it decays through the 269- and 339-keV
E2- and E3-type transitions, respectively. Moreover, a cascade of magnetic dipole transitions that is suggested
to originate from a shears band was observed by using recoil-gated γ − γ (−γ ) coincidence techniques.
