摘要：
An iron-free beta spectrometer with pre- and post-acceleration of electrons was used to study beta branches and conversion electrons at very low energies in the beta decay of Ra-228. Results of conversion-electron and gamma-ray spectroscopy are analyzed using beta selection rules and two-quasiparticle-rotor model considerations. A tentative Ac-228 level scheme, including model-dependent spin-parity and configuration assignments consistent with the available data, is presented.
