Quizplus · Accepted Answer

The reaction involves an electron (represented as e) being captured by the Cs nucleus, resulting in the conversion of a proton (55) to a neutron (54). This is characteristic of electron capture, making answer choice D the best option. Beta emission involves the release of a high-energy electron from the nucleus, positron emission involves the release of a positive electron from the nucleus, gamma emission involves the release of a high-energy photon from the nucleus, and alpha capture involves the capture of an alpha particle by the nucleus. None of these processes are occurring in this reaction.
