چکیده انگلیسی
We use the well-known Wentzel-Kramers-Brillouin (WKB) barrier penetration probability to calculate α-decay branching ratios for ground and excited states of heavy even-even nuclei of Fermium (248-254Fm), Californium (244-252Cf), Curium (238-248Cm) and Plutonium (234-244Pu) with 94â¤Zpâ¤100. We obtained the branching ratios for the excited states of daughter nucleus by the α-decay energy (Qα), the angular momentum of α-particle (âα), and the excitation probability of the daughter nucleus with the excitation energy of state â in the daughter nucleus (i.e. Eââ). α-Decay half-lives have been evaluated by using the proximity potential model for the heavy even-even nuclei. We have reported the half-lives and compared the results with the experimental data. The theoretical branching ratios of α-transitions in our calculation are found to agree with the available experimental data well for 0â+ 0+, 0â+ 2+, 0â+ 4+, 0â+ 6+ and 0+ â 8+α-transitions.
