The electrostatic fields were created by charging SiO2 layers patterned on the carrier and the chips. Pedestal-cavity mating-structures were employed as spacers to avoid premature sticking and ensure unique alignment position. Vertical vibration was applied to stochastically move the chips. During 10 repetitive experiments, 16 dummy-chips with dimension 2times2 mm were accurately aligned on the carrier within an average of 30 seconds and standard deviation of 11 seconds. This method can be used to batch assemble different types of chips, e.g. by carrier-to-carrier transfer, in dry environment with high accuracy and low cost.

Several new side bands as well as the yrast band were established. The first band crossings both in the yrast sequence and in the even-spin sequence of the γ-band were observed at ħω c= 0.39 MeV and ħω c = 0.31 MeV respectively. The γ-dependent cranked shell-model calculation was performed to interpret the band crossing in the γ-band.

Several new side bands as well as the yrast band were established. A band crossing between the ground state and super bands was observed at ħωc = 0.39 MeV. A negative parity band with two quasi particle excitation, and a quasi γ band were also identified.
