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, can be calculated within analytical superasymmetric fission model, by taking into account the angular momentum of the emitted cluster. Detailed tables are presented for 14 C radioactivity of 221 Fr, 221,223 Ra, 225 Ac; 24 Ne radioactivity of 233 U, 231 Pa, and 23 F decay of 231 Pa, showing that, except for 225 Ac, the existing experimental evidences, do not exclude (moderate) hindered transitions to the ground states of the daugther nuclei.
