✦ Synopsis

Theoretical results are presented for nuclear excitation of low-lying isometric states of 197 Au, 189 Os and 237 Np by a near-resonant electronic deexcitation process known as NEET. A detailed comparison is made between current and previous theoretical results in order to clarify a number of anomalies. For 197 Au, the only case in which the current experimental precision appears to be sufficient to provide a stringent test of theory, the theoretical result for the NEET probability is P NEET = 3.6 × 10 -8 . This is a factor of three lower than previous theoretical results and reduces the difference between theory and the recent experimental result, P NEET = (5.0 ± 0.6) × 10 -8 , to a level of approximately 2σ .
