Description

Branching ratios of $α$-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 $α$-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$\geq 224$. The calculated branching ratios of the $α$-transitions are in good agreement with the experimental data and some useful predictions are provided for future experiments.
