Abstract：
The properties of the nuclei belonging to the newly discovered alpha-decay chain starting from Bh have been studied. The axially deformed relativistic mean field (RMF) calculation with the force TMA and NL-Z2 has been performed in the blocked BCS approximation. Some ground state properties such as the binding energies, deformations, spins and parities, as well as Q-values of the alpha decay for this decay chain have been calculated and compared with known experimental data. Good agreement is observed. The single-particle spectrum of the nucleus Bh has been studied.
