We present experimental results on the ionization/dissociation of methane in femtosecond pulses of radiation. Angular and intensity dependent yields of singly and doubly charged species were measured using an imaging mass spectrometer. The measured data shows that all fragments yields exhibit some degree of anisotropy as a result of them being preferably ejected parallel to the polarization direction. Additionally, an anomalous perpendicular fragmentation pattern is found for CH\-(2)\+(2+). We…

Chirping-dependent ionization and dissociation of methane in an intense femtosecond laser field

We studied the ionization and dissociation of polyatomic molecule methane in an intense femtosecond laser field with wavelength of 810 nm and intensities ranging from 1.4×10^(14) to 2.6×10^(15) W/cm2

Ionization of methane in strong and ultrastrong relativistic fields.

The photoionization of methane is reported for intensities up to 10(19) W/cm2 with linear and circular polarized light, and removal of a carbon K-shell electron from methane proceeds via tunneling and rescattering ionization, without the influence of molecular channels.
