Several physical models have been proposed to account for this suppression, while no consensus has been achieved. In this Letter, we aim to clarify the underlying mechanisms behind this molecular ionization suppression. Experimental data recorded at midinfrared laser wavelength and its comparison with that at near-infrared wavelength revealed a peculiar wavelength and intensity dependence of the suppressed ionization of O-2 with respect to its companion atom of Xe, while N-2 behaves like a structureless atom. It is found that the S-matrix theory calculation can reproduce well the experimental observations and unambiguously identifies the significant role of two-center interference effect in the ionization suppression of O-2. ¹Ø¼ü´Ê KeyWords Plus:MULTIPHOTON IONIZATION; DYNAMICS; SINGLE ×÷ÕßÐÅÏ¢ ͨѶ×÷ÕßµØÖ·: Lin, ZY (ͨѶ×÷Õß) Chinese Acad Sci, State Key Lab Magnet Resonance & Atom & Mol Phys, Wuhan Inst Phys & Math, Wuhan 430071, Peoples R China. µØÖ·: [ 1 ] Chinese Acad Sci, State Key Lab Magnet Resonance & Atom & Mol Phys, Wuhan Inst Phys & Math, Wuhan 430071, Peoples R China [ 2 ] Chinese Acad Sci, State Key Lab High Field Laser Phys, Shanghai Inst Opt & Fine Mech, Shanghai 201800, Peoples R China [ 3 ] SW Jiaotong Univ, Quantum Optoelect Lab, Chengdu 610031, Peoples R China [ 4 ] Peking Univ, Ctr Appl Phys & Technol, Key Lab High Energy Dens Phys Simulat, Beijing 100084, Peoples R China [ 5 ] Inst Appl Phys & Computat Math, Beijing 100088, Peoples R China [ 6 ] Chinese Acad Sci, Grad Sch, Beijing 100080, Peoples R China µç×ÓÓʼþµØÖ·:xjliu@wipm.ac.cn; chen_jing@iapcm.ac.cn; ycheng-45277@hotmail.com; zzxu@mail.shcnc.ac.cn »ù½ð×ÊÖúÖÂл »ù½ð×ÊÖú»ú¹¹ ÊÚȨºÅ NNSF of China 10925420 11134010 10904162 11074026 11104225 60825406 11174330 National Basic Research Program of China 2011CB8081002 ²é¿´»ù½ð×ÊÖúÐÅÏ¢ ³ö°æÉÌ AMER PHYSICAL SOC, ONE PHYSICS ELLIPSE, COLLEGE PK, MD 20740-3844 USA Àà±ð / ·ÖÀà Ñо¿·½Ïò hysicsWeb of Science Àà±ð hysics, MultidisciplinaryÎÄÏ×ÐÅÏ¢ ÎÄÏ×ÀàÐÍ:Article ÓïÖÖ:English Èë²ØºÅ: WOS:000304531100006 ISSN: 0031-9007 ÆÚ¿¯ÐÅÏ¢ Ŀ¼£º Current Contents Connect® Impact Factor (Ó°ÏìÒò×Ó): Journal Citation Reports® ÆäËûÐÅÏ¢ IDS ºÅ: 948VO Web of Science ºËÐĺϼ¯ÖÐµÄ "ÒýÓõIJο¼ÎÄÏ×": 33 Web of Science ºËÐĺϼ¯ÖÐµÄ "±»ÒýƵ´Î": 10 |
