Nuclear level excitation during charge nonconservation
The possibility of nuclei being excited during charge nonconservation was investigated. The process studied is analogous to nuclear K capture which does not change a nucleon's charge state but which does leave the nucleus in an excited state. We searched for ..gamma.. rays emitted by /sup 127/I nuclei and detected in a 25.4 cm x 20.3 cm diam NaI(Tl) counter. Our most conservative limit for the charge nonconserving lifetime tau/sub CNC/ for this mechanism is tau/sub CNC/greater than or equal to1.9 x 10/sup 21/ yr. The results can be used to place limits on the charge nonconservation mechanism in weak interactions where a neutrino replaces an electron in the (e,e) current, and where a proton replaces a neutron in the (p,n) current.
