Based on the previous work, two expansion formulas of fully symmetric wavefunction for describing three bosons in different orbits are obtained, which can be used to calculate the nuclear specturm.
Based on the cluster structure of 4n-nucleus, a parity-dependent potential is derived by using a proper nuclear orbital wavefunction and the folding method.
By making use of the strong bound quantum dot model and neglecting the effects of impurity on electron wavefunction, this thesis is also reported how to use the spin of nuclear as the quantum bit.
