CLUSTER RADIOACTIVITIES OF ODD-MASS NUCLEI

The partial half-lives of the hypothetical even-even equivalent of an odd-mass nucleus for cluster transitions toward various excited states of the daughter, used as a reference to find the hindrance factor, ca n be calculated within analytical superasymmetric fission model, by ta king into account the angular momentum of the emitted cluster. Detaile d tables are presented for C-14 radioactivity of Fr-221, Ra-221, Ra-22 3, Ac-225; Ne-24 radioactivity of U-233, Pa-231, and F-23 decay of Pa- 231, showing that, except for Ac-225, the existing experimental eviden ces, do not exclude (moderate) hindered transitions to the ground stat es of the daugther nuclei.
