Abstract :
Theoretical results are presented for nuclear excitation of low-lying isometric states of 197Au, 189Os and 237Np 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 197Au, 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 View the MathML source. This is a factor of three lower than previous theoretical results and reduces the difference between theory and the recent experimental result, View the MathML source, to a level of approximately 2σ.
