Probing electron localization during molecular dissociation by femtosecond strong-field ion momentum spectroscopy

open access: yesCommunications Physics, 2023
The study of molecular valence electron dynamics and their coupling with nuclear motion is one of the frontiers of ultrafast physics and ultrafast chemistry. With time-resolved strong-field ion momentum spectroscopy, we study electron valence and nucleus

Exploring Enhanced 12C Production in Astrophysical Environments through Inverse Maxwellian Averaged Reaction Rate [PDF]

open access: yesEPJ Web of Conferences
A significant increase in stable 12C production can result from lightparticle- induced deexcitation from resonances above the 3α breakup threshold. The enhancement in 12C production has been calculated in the temperature range of T9 = 0.1 to 10 using the

Nuclear Polarizabilities and Logarithmic Sum Rules [PDF]

open access: yes, 1997
The electric polarizability and logarithmic mean-excitation energy are calculated for the deuteron using techniques introduced in atomic physics. These results are then used to improve limits on the atomic-deuterium frequency shift due to nuclear ...

Meson and Quark Degrees of Freedom and the Radius of the Deuteron [PDF]

open access: yes, 1996
The existing experimental data for the deuteron charge radius are discussed. The data of elastic electron scattering are inconsistent with the value obtained in a recent atomic physics experiment.
