✦ Synopsis

∆ (Q(β -))=643, ∆ (S(n))=861, ∆ (S(p))=501, ∆ (Q(α ))=428 (syst,1995Au04). Q(ε p)=3283 402 (syst,1995Au04). 143 Tb produced in 112 Sn( 35 Cl,2n2p) E=191 MeV (1985Ol01). Others: 1987Pl05, 1986Re11, 1982Gu07. 143 Tb Levels Band configurations are given according to quasiparticle labels: upper-case letters represent quasiproton orbitals and lower-case letters represent quasineutron orbitals.

T 1/2 : from 1986Re11 (also 1987Pl05).

J π : ε decay to (9/2-,11/2-); syst for 11/2-levels in Z=65 nuclei.

0+ x ? <2 1 s %ε +%β + =? J π : (5/2+) from systematics (1997Au04).

T 1/2 : from analysis (by 1986Re11) of T 1/2 (45γ from 45 level in 143 Gd). 1986Re11

suggest T 1/2 =17 s 4 (if there is no isomeric γ between (11/2-) and (5/2+) states and (5/2+) is directly populated in (HI,xnγ ) reaction) or ≈ 12 s if there is isomeric γ between (11/2-) and (5/2+) states. However, there seems no evidence from recent in-beam gamma-ray experiments, that a 5/2+ state is populated.
