The internal transition decay and α decay of the $T_{1/2} = 53.3$ ms, $9/2^-$ isomeric state in the neutron-deficient isotope, $^{183}$Tl, have been studied using the Resonance Ionization Laser Ion Source and the Windmill detection setup at the ISOLDE facility at CERN. Clean samples of $^{183}$Tl were produced by selective laser ionization and subsequent mass separation. [...]

Change in structure between the $I = 1/2$ states in $^{181}$Tl and $^{177,179}$Au
/ Cubiss, J G (York U., England ; CERN) ; Barzakh, A E (Kurchatov Inst., Moscow) ; Andreyev, A N (York U., England ; JAERI, Tokai ; CERN) ; Al Monthery, M (York U., England) ; Althubiti, N (Manchester U.) ; Andel, B (Comenius U.) ; Antalic, S (Comenius U.) ; Atanasov, D (Heidelberg, Max Planck Inst.) ; Blaum, K (Heidelberg, Max Planck Inst.) ; Cocolios, T E (Leuven U. ; Manchester U. ; CERN) et al.
The first accurate measurements of the $\alpha$-decay branching ratio and half-life of the $I^{\pi}=1/2^+$ ground state in $^{181}$Tl have been made, along with the first determination of the magnetic moments and $I=1/2$ spin assignments of the ground states in $^{177,179}$Au. The results are discussed within the complementary systematics of the reduced $\alpha$-decay widths and nuclear $g$ factors of low-lying, $I^{\pi}=1/2^+$ states in the neutron-deficient lead region.
