Abstract The α decay constant is the product of the penetrability P and assault frequencyν0 in the fission-like model. An effective assault frequency Pν replacing the previous assault frequency ν0 is introduced for improvement of a fission-like model named the generalized liquid drop model (GLDM) to describe the nuclear α decay process more accurately. Two analytical formulae are proposed for the effective assault frequency due to experimental data within the GLDM. The improved model can be used to give accurate calculations for α decay half-lives.
