查询词典 widths

Using these constants and QFT〓 method, we calculated the N〓-broaden widths of the observed absorption lines for (202) band. Also we obtained the N〓-broaden widths and temperature dependences of lines in the 〓R (1, 1) branch of (202),(122), and (004) bands.

In chapter 2 and 3, experimentally, using the Angular-Resolved high-resolution fast Electron Energy Loss Spectrometer , at the condition of 2. 5 keV incident energy and 50-60 meV energy resolution, we measured the Optical Oscillator Strength Density Spectra for the excitations of 4p, 4s or 3d electron. The oscillator strengths for excitations of the valent shell 4p electron were obtained, and comparisons were done between presently experimental and previously experimental and theoretical results. The experimental results of different groups agree with each other approximately, but the semi-experientially theoretical results do not match with the experimental results. The delayed maximum in the photoabsorption spectra was discussed. It should arise from the transition of 4p→∈d. For the excitation of the inner-valent 4s electron, the discrepancies for the resonant structures in previous electron-impact results and photoionization results were clarified in present work, which confirms again that the fast electron impact method is suitable to measure the optical oscillator strengths. The autoionization Rydberg series 4s〓ns (n=5, 6, 7) and 4s〓nd (n=4, 5, 6, 7) were identified without ambiguity by the measurement at 0°, 2° and 4°scattering angles. The energy levels and natural widths of the excitations of Kr3d and Ar2p inner shell, including optically allowed and forbidden transitions, were determined. The widths of these inner shell excitations are nearly the same, which was interpreted by the Resonant Auger effect .

在第二章和第三章，实验上，使用角分辨的高能量分辨快电子能量损失谱仪，在2.5keV电子入射能量和50-60meV能量分辨下，测量了Kr原子由价壳层4p到内价壳层4s，再到内壳层3d电子激发的光学振子强度密度谱；得到了价壳层4p电子激发束缚态的光学振子强度，与前人实验和半经验理论结果作了细致的比较，说明几家实验是比较符合的，但半经验的理论计算存在问题；分析了光吸收谱中的延迟极大现象，说明在第一电离阈值以上几个eV范围内的极大值源于4p→εd跃迁产生的延迟极大；对于内价壳层4s激发的自电离区，澄清了前人实验中电子碰撞方法和光学方法在共振结构上存在差异的问题，再一次肯定了快电子碰撞方法是获得绝对光学振子强度的一种好方法；通过在非0°散射角的测量（如2°和4°），清楚地标识了4s电子激发的光学禁戒跃迁自电离里德堡系列4s〓ns（n=5，6，7）和4s〓nd（n=4，5，6，7）；通过在0°和4°散射角的测量，观测并标识了几个新的内壳层光学禁戒跃迁能级，得到了Kr原子3d和Ar原子2p内壳层激发态（包括光学允许和禁戒跃迁形成的）的能级位置和自然宽度，用共振俄歇效应解释了这些内壳层激发态（不管是光学允许还是禁戒跃迁产生的）的自然宽度彼此比较接近的原因。

At typical plasma conditions (such as a temperature of 10eV and a density of 0.0016g/cm〓), these autoionization widths are larger than corresponding Doppler and Stark widths by a factor of two or three.

研究了O Ⅲ离子基组态2s〓2p〓和第一激发组态2s2p〓所形成的谱项的内壳层光电离过程，由光电离截面所展现的共振结构，确定了1s-2p内壳层激发态的自电离宽度，结果表明，在某些典型的氧等离子体条件，自电离共振展宽是等离子体中主要的谱线展宽机制。

For an aluminum plasma at a temperature of 40eV and a density of 0.0135 g/cm〓, the widths of the K-shell 1s-2p excited autoionization states of aluminum ions are larger than the widths caused by the Doppler and Stark broadening. Therefore, the autoionization resonance broadening is one of the main broadening mechanisms of spectral lines.

研究表明，对温度为40 eV，密度为0.0135g/cm〓的铝等离子体，1s-2p内壳层激发态的自电离共振宽度往往超过由Doppler展宽效应引起的宽度，因而前者是主要的谱线展宽机制之一。
