Ion-pair formation in gaseous nitromethane (CH(3)NO(2)) induced by electron transfer has been studied by investigating the products of collisions between fast potassium atoms and nitromethane molecules using a crossed molecular-beam technique. The negative ions formed in such collisions were analysed using time-of-flight mass spectroscopy. The six most(More)
The first ab initio calculations of the vertical excitation energies and oscillator strengths are presented for the neutral electronic transitions of methyl formate, C(2)H(4)O(2). The highest resolution VUV photoabsorption spectrum of the molecule yet reported is presented over the wavelength range 115 to 310 nm (10.8 to 4.0 eV) revealing several new(More)
Iterative image restoration algorithms can better control the restoration process, but the choice of the relaxation parameters can be an inviable task. We present here a GP-based approach that stabilizes the iterative RAP-2D image restoration algorithm choosing the optimal or quasi-optimal relaxation parameters that maximize the improvement signal to noise(More)
