Abstract

From the observed competition between M1 and E2 gamma transitions deex citing the states of the two signature partner yrast superdeformed ban ds in (193)T1, the i(13/2) (Omega=5/2) intruder proton orbital is foun d to have (g(K) -g(R))K/Q(0) = 0.138 +/- 0.008. A model dependent valu e of g(s)(eff) =(0.7 +/- 0.2)g(s)(free) is deduced. A saturation of th e J(2) moments of inertia, at rotational frequency h omega > 0.32 MeV, is observed for the two bands. This feature is discussed in terms of exhausted quasineutron alignment in the presence of substantially redu ced quasiproton alignment due to Pauli blocking.
