By using the multi - configuration dirac - fock ( mcdf ) method, the effects of relaxation and correlation on the transition energies and probabilities of electric - dipole allowed ( el ) resonance and intercombination transitions for 2p53s3 - 2p6 in neutral neon have been systematically studied firstly. and the results of the transition energies and probabilities ( lifetimes ) in length and velocity gauge have been presented. during the calculation, in order to consider the rearrangement effects of the bound - state density and some important correlations, the asfs of transition initial - and final - states were divided according to their angular - momentum and parity and calculated, and different number of csfs were included in the expansion of asfs

  4. First, we study electromagnetically induced absorption. this significant feature of the system model is that a four - level system in which three - dipole transitions are in n configuration in this system, the middle transition serves as a probe transition and two other transitions serve as couple transitions

    系統的模型特徵是：三個電偶極躍遷構成n型鏈的四能級系統，其中，中間躍遷為探測躍遷，兩邊的躍遷為耦合躍遷。
  5. And during the transition, the field retains its dipole shape, a phenomenon paleomagnetists have traced all the way to the south pole

    在翻轉期間，磁場保持它的雙極子外形，保留了古磁學家一直能夠追蹤南極蹤跡的現象。
  6. According to the dipole transition selection rule, it allows the system to transit from the ground state to the first and second sub - band respectively, the shape of the photoionization cross - section varying with the photon energy in the two cases is quite different

    根據偶極躍遷的選擇定則，將使得體系從基態分別躍遷到電子的第一子帶和第二子帶，二者的光電離截面隨光子能量的變化截然不同。
  7. We consider two situations : ( i ) the light is polarized along the z - direction, in which case the first allowed dipole transition is to the first subband ( nx - 1, ny = 1 ) ; ( ii ) the light is polarized along the x - direction ( paralleled to the transverse cross - section of the wire ). the first allowed dipole transition is to the second subband nx = 2 relative to the x - direction and to the first subband nr = 1 relative to the y - direction of the wire
