Relaxation behavior of vibrationally excited N2 (X1Σg+v” = 6) induced by collisions with H2 has been investigated using coherent anti-Stokes Raman spectroscopy (CARS). The total pressure of the N2–H2 mixture was 500 Torr, and the molar ratios of H2 we…
Spectral lines of buffer noble gases injected into an electron beam ion trap (EBIT) have recently been used as a reference to aid accurate determination of the wavelengths of optical transitions of highly charged ions (HCIs). Simultaneous observation o…
The properties of a hydrogen atom inside a non-ideal classical plasma, in terms of its behavior in the presence of an applied laser pulse, are explored. The strength of the pulse is chosen such that it maintains near sphericity of the system. The pulse…
Understanding the interactions between atoms and light is at the heart of atomic physics. Being able to ‘experiment’ with various system parameters, produce plots of the results and interpret these is very useful, especially for those new to the field….
This article investigates the radiolysis of a mixture of nitric acid with water (HNO3:H2O) at 16 K in high-vacuum (residual pressure < 10−6 mbar). A nitric acid-water ice film was exposed to 40 MeV 58Ni11+ ion beam in a heavy ion accelerator facilit…
We present an experimental setup for probing chemical changes in liquids induced by electron collisions. The setup utilizes a custom-designed electron gun that irradiates a liquid microjet with an electron beam of tunable energy. Products of the electr…
The three condensate wavefunctions of a F = 1 spinor Bose–Einstein condensate on a spherical shell can map the real space to the order-parameter space that also has a spherical geometry, giving rise to topological excitations called lump solitons. The …
To better understand the structure of the open 4{\text{f}} shell, the spectroscopic data in the 420–600 nm range of the highly charged ions of W24+ obtained with an electron beam ion trap are presented. Detailed collisional-radiative (CR) modeling has …
We evaluate the rate of the absorption of an optical nanofibre mode by a Cs atom in an electric quadrupole transition. With the Cs atom localised near the outer surface of the optical nano-fibre, an interaction occurs between the atomic quadrupole tens…
We compute the Bogoliubov–de Gennes excitation spectrum in a trapped two-component spin-orbit-coupled (SOC) Bose–Einstein condensate (BEC) in quasi-two-dimensions as a function of linear and angular momentum and analyze them. The excitation spectrum ex…
