摘要

Branching ratios of alpha decay to members of the ground state rotational band and excited 0( ) states of even-even nuclei are calculated in the framework of the generalized liquid drop model (GLDM) by taking into account the angular momentum of the alpha particle and the excitation probability of the daughter nucleus. The calculation covers isotopic chains from Hg to Fm in the mass regions 180 < A < 202 and A >= 224. The calculated branching ratios of the alpha transitions are in good agreement with the experimental data and some useful predictions are provided for future experiments.
