In this paper we discussed the behavior of a hydrogen atom in moving and found there is a speed threshold for hydrogen atom. As long as the speed of hydrogen re
Level structure, oscillator strengths, transition probabilities and radiative life times are evaluated for 1s2 2s2 2p63l, 4l, 5l (l = 0, 1, 2, 3, 4) states in s
Photothermal deflection spectroscopy is a method used indirectly to measure optical absorption of a sample. Different techniques can be employed to measure the
We first analyze the sech-shaped soliton solutions, either spatial or temporal of the 1D-Schr?dinger equation with a cubic nonlinearity. Afterwards, these solut
