Alpha and cluster decay half-lives in Tungsten isotopes: A microscopic analysis

Alpha and cluster decay half-lives of Tungsten (W) isotopes in the range between 2p drip line and beta stability line are studied. The sensitivity of different Skyrme parametrizations in predicting the alpha decay and probable cluster decay modes from W isotopes have been analysed. The half-lives are calculated using Universal Decay Law (UDL). Predicted half-lives are compared with Effective Liquid Drop Model (ELDM) and also with available experimental values. The use of harmonic oscillator (HO) and transformed harmonic oscillator (THO) basis do not produce much differences in the results. The study also revealed the role of neutron shell closure in cluster decay process.
