Write the basic principle of Rutherford backscattering spectroscopy (RBS) also name the ions commonly used for primary beam in RBS.
Explain why neutron induced reactions are most common whereas deuteron induced reactions require accelerator facility to carry out these reactions.
In a coulometric method, 200 mg of nitrobenzene in of methanol is reduced to phenyl hydroxylamine at a constant potential of -0.95 V (vs. SCE) applied to an Hg electrode. Following reaction takes 30 minutes to complete.
$
Calculate the percentage of nitrobenzene if above reduction requires 32mA current.
Indium and Cadmium ions in 0.1 M HCl give peaks at potentials -0.557 V and -0.597 V by differential pulse polarographic analysis. When a standard solution containing 0.4 ppm of indium is analysed, it gave peak current (in arbitrary units) corresponding to 100.25 at -0.557 V and 43.75 at -0.597 V. A standard solution containing 0.4 ppm of Cd gave ip 29.52 at -0.557 V and 64.8 at -0.597 V. What is the concentration of indium and cadmium in a sample if the peak current is 190 at -0.557 V and 120 at -0.597 V.
