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
本文利用多組態dirac - fork ( mcdf )理論方法,通過對輻射躍遷初、末態電子波函數的獨立計算以及在原子態波函數的展開中考慮不同數量的組態波函數,系統地研究了弛豫和相關效應對中性ne原子2p ~ 53s ~ ( 1 . 3 ) p _ 1 ~ o - 2p ~ 6 ~ 1s _ 0電偶極共振和復合躍遷的能量以及躍遷幾率的影響,給出了長度和速度兩種不同規范下激發態的能量和輻射壽命;以中性ne原子的研究為基礎,進一步研究了類ne等電子系列離子( z = 11 - 18 )較低的激發組態2p ~ 53s和基組態2p ~ 6的能級結構以及各能級間的輻射躍遷特性。Then, we establish the finite element analysis models of the antenna in different structure layout, and obtain the corresponding frequencies and model shapes. finally, according to the importance of each object, we set up the model of multiple objects that aims to maximize the first natural frequency and minimize the mass. combining orthogonal experiment and variant weighting coefficient method, we formed an effective multiple objects optimized algorithm basing on the neural network and genetic algorithm
