Elastic scattering properties of singlet and triplet states of7 Li133 Cs at ultralow temperatures are calculated using the constructed potential curves gleaned from high-precision spectroscopy measurement. We show how to reach the scattering length a

To quantify the changes of the geometric shielding effect in a molecule as the incident electron energy varies, we present an empirical fraction, which represents the total cross section (TCS) contributions of shielded atoms in a molecule at differen

Considering the real experimental process of e-molecule scattering a new empirical formula has been developed to calculate the total cross sections (TCSs) for electron scattering on polyatomic molecules (CH4, C2H2, CH3OH and CH3F). The present result

A complex optical model potential correlated by the concept of bonded atom, which considers the overlapping effect of electron clouds between the two atoms in a molecule, is employed to calculate the total cross sections for electron scattering from

We present an improved radiative pumping model for interstellar H2O and OH masers. This overcomes the defects of former radiative models, and is compatible with astronomical conditions. For the regions of strong H2O and OH formation, it is shown that

A nonchaotic attractor is observed in an infinite-dimensional system which is related to optical bistability and described by a nonlinear time-delay differential equation. The observed nonchaotic attractor is characterized by the strange trajectory o

Theoretical calculation of the differential cross section (DCS) for elastic electron–helium scattering in the presence of a bichromatic CO2 laser field is carried out in the first Born approximation with a simple screening electric potential. The t

The spectral absorption features of three amphetamine-type stimulants (ATS) belonging to illicit drugs have been studied with terahertz (THz) time-domain spectroscopy (THz-TDS) and the characteristic absorption spectra (fingerprint spectra) are obtai

Electron scattering from spherical polyatomic molecules in the intermediate and high energy range is studied by employing the developed semi-empirical formula for electron scattering from simple diatomic molecules. The total cross sections of electro
