Abstract

Excited states in the odd-odd nucleus ²¹²At have been studied using γ-ray and electron spectroscopy following the ²⁰⁸Pb(⁷Li,3n) reaction. Levels were identified to spins of 25ℏ and to excitation energies of about 4.8 MeV. New isomeric states which decay by enhanced E3 transitions have been established at spins 18⁺, 22^- and 25^-. Shell model calculations reproduce well the main features of the level scheme and show the configuration dependence of certain empirical residual interaction matrix elements.
