Abstract: | The triaxial deformation in 10Be is investigated using a microscopic α+α+n+n model. The states of two valence neutrons are classified based on the molecular-orbit (MO) model, and the π orbit is introduced about the axis connecting the two α clusters for the description of the rotational bands. There appear two rotational bands comprised mainly of Kπ=0+ and Kπ=2+, respectively, at low excitation energy, where the two valence neutrons occupy Kπ=3/2- or Kπ=1/2- orbits. The triaxiality and the K mixing are discussed in connection to the molecular structure, particularly to the spin-orbit splitting. The extent of the triaxial deformation is evaluated in terms of the electromagnetic transition matrix elements (Davydov-Filippov model, Q-invariant model) and density distribution in the intrinsic frame. The obtained values turned out to be γ=15°–20°. |
