中文摘要：
钛原子的提高回声的 multiphoton 电离在 293321 nm 波长被调查了。我们联合一个切除激光的金属目标进一根分子的横梁生产免费原子。从中立原子的光电游离生产的离子被一个造家的 time-of-flight 团分光计监视。Ti 的激动的状态的光电游离生气的节我近为光子精力在激光紧张上从离子信号紧张的依赖被推出到电离阀值。获得的价值从 0.2 Mb 到 6.0 Mb。没有重要同位素依赖从 46Ti， 47Ti，和 48Ti 的光电游离十字节的大小被发现。
英文摘要：
Resonance-enhanced multiphoton ionization of the titanium atoms has been investigated in the 293 321 nm wavelength. We couple a laser-ablated metal target into a molecular beam to produce free atoms. Ions produced from photoionization of the neutral atoms are monitored by a home-built time-of-flight mass spectrometer. Photoionization cross sections of the excited states of Ti I were deduced from the dependence of the ion signal intensity on the laser intensity for photon energies close to the ionization threshold. The values obtained range from 0.2 Mb to 6.0 Mb. No significant isotope-dependence was found from measurements of the photoionization cross sections of ^46Ti, ^47Ti, and ^48Ti.
