Spectroscopy of ²⁰¹At including the observation of a shears band and the 29/2⁺ isomeric state

NUCLEAR REACTIONS ¹⁶⁵Ho(⁴⁰Ar, 4n)²⁰¹At, E=172 MeV; measured Eα, Eγ, Iγ, γγ-, (ce)γ-, (recoil)γ-coin, isomer half-life by (recoil)γγ(t), γ(θ) using RITU separator and JUROGAMII array at Jyvaskyla accelerator facility. ²⁰¹At; deduced high-spin levels, J, π, K/(L+M+..) ratios, multipolarity, B(M1)/B(E2), B(E2), B(E3), configurations, magnetic-dipole rotational (shears) band. Systematics of energies and B(M1)/B(E2) values in N=110-126, odd-A At and even-A Po nuclei.
