Exploration of strong-field double ionization of C_3H_6 with the structures of propene and cyclopropane in intense laser fields 下载免费PDF全文
By using classical ensemble method, we investigate the double ionization of C_3H_6 molecule with different structures(propene and cyclopropane) in intense laser fields. The numerical results show that the non-sequential double ionization occurs in propene molecule rather than cyclopropane molecule in 1200 nm laser field. To further explain this interesting phenomenon, the momentum distribution of double ionized electrons is presented and the result presents the "finger-like" structure at about 30 TW/cm~2 of propene molecule, and this structure is more obvious than that in cyclopropane molecule.The above phenomena are also demonstrated by analysing the energy distributions of double-ionized electrons versus time. Moreover, we also investigated the angular distribution at the end of pulse, which is different between propene and cyclopropane. 相似文献
