ATOMIC EXCITATION EFFECTS ON NUCLEAR RESONANCES AND Q-VALUES

Atomic excitation effects in nuclear interactions are studied in. terms of the moments of the energy distribution of the atomic electrons by using sum rules which allow calculation of modifications to nuclear resonance line shapes and to β+-decay Q-values determined from (p,n) threshold energies. These modifications may be observable with current experimental precision. A previous low-energy resonance experiment is reviewed in terms of sum rules, and feasible high-precision resonance experiments using small accelerators are suggested. Modifications to β+-decay Q-values are given for cases relevant to tests of weak-interaction theories. Copyright © 1978 by The Institute of Electrical and Electronics Engineers, Inc.
