Abstract

From the observed competition between M1 and E2 γ transitions deexciting the states of the two signature partner yrast superdeformed bands in 193T1, the i13/2 (Ω= 5/2) intruder proton orbital is found to have (gK -gR)K/Q0=0.138±0.008. A model dependent value of geffs=(0.7±0.2)gfrees is deduced. A saturation of the script T sign2 moments of inertia, at rotational frequency hω>0.32 MeV, is observed for the two bands. This feature is discussed in terms of exhausted quasineutron alignment in the presence of substantially reduced quasiproton alignment due to Pauli blocking.
