Abstract
The [Formula: see text]-decay chain of [Formula: see text] and [Formula: see text] is studied using cubic plus proximity potential with improved transfer matrix (CPP-ITM) model. The nuclear mass models DD-PC1, WS4, WS3.3 are employed to evaluate the [Formula: see text]-decay energies. Thus calculated [Formula: see text]-decay half-lives and decay chain lengths are found to be in good agreement with other theoretical formalisms. The spontaneous fission (SF) half-lives are calculated using the formalism of Xu et al. [Phys. Rev. C 71 (2005) 014309; Phys. Rev. C 78 (2008) 044329] to have a vision on the possible decay modes and decay chain lengths, and the most probable decay chains associated with the isotopes of [Formula: see text] [Formula: see text] [Formula: see text]. This paper unveils the mass region that survives fission and also predict the long [Formula: see text]-decay chains of [Formula: see text] [Formula: see text] [Formula: see text] with [Formula: see text] emitting 6[Formula: see text], [Formula: see text] emit 5[Formula: see text] [Formula: see text] [Formula: see text] 4[Formula: see text] particles, while for [Formula: see text] chains will have [Formula: see text] emission. The SF for [Formula: see text] [Formula: see text] [Formula: see text] occur at [Formula: see text] and [Formula: see text]. These current predictions may pave way to detect/synthesize the most probable isotopes of the superheavy elements [Formula: see text] [Formula: see text] [Formula: see text] in the laboratory through future experiments.
