辐射寿命的英文
例句与用法
- The spectra parameters of these crystals can be calculated by the f - l formula , which show that the crystals are applicable for the tunable laser and femtosecond laser because of their large emission broadband ( fwhm 50nm )
用f ? l公式计算了晶体yb3 +的2f7 / 2 2f5 / 2能级跃迁的发射截面、辐射跃迁几率、辐射寿命等光谱参数。 - 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
本文利用多组态dirac - fork ( mcdf )理论方法，通过对辐射跃迁初、末态电子波函数的独立计算以及在原子态波函数的展开中考虑不同数量的组态波函数，系统地研究了弛豫和相关效应对中性ne原子2p ~ 53s ~ ( 1 . 3 ) p _ 1 ~ o - 2p ~ 6 ~ 1s _ 0电偶极共振和复合跃迁的能量以及跃迁几率的影响，给出了长度和速度两种不同规范下激发态的能量和辐射寿命；以中性ne原子的研究为基础，进一步研究了类ne等电子系列离子( z = 11 - 18 )较低的激发组态2p ~ 53s和基组态2p ~ 6的能级结构以及各能级间的辐射跃迁特性。
