Title: Structure of /sup 209/Bi deduced from the /sup 208/Pb(t,2n. gamma. ) reaction

Abstract

States in /sup 209/Bi were populated with the /sup 208/Pb(t,2n) reaction. Incident triton energies between 11 and 16 MeV were used. Gamma-ray excitation functions, angular distributions, and ..gamma..-..gamma..-time coincidence spectra were measured. Approximately 50 newly-observed ..gamma.. rays have been assigned to transitions in /sup 209/Bi. Previously-unresolved doublets at E/sub x/ = 2600, 3135, and 3154 keV have been identified. A new level at 3270 keV is reported, and the 3197-keV level is verified. /sup 209/Bi level energies are reported with an accuracy of 600 eV or less. A level scheme for E/sub x/<4.14 MeV is presented, including spin-parity assignments. A new M1 transition between the (5/2)/sup +/ and (3/2)/sup +/ members of the ..pi..h/sub 9/2/x3/sup -/ septuplet is reported. The 19 levels belonging to the ..nu..g/sub 9/2/p/sub 1/2/ /sup -1/, ..pi..h/sub 9/2/ are identified.
