- The isotope of Nickel, 66Ni decays by β emission, has a half-life of 2.3 days. and the β particles have an average energy of 65 keV. A source consisting of this isotope has an initial number of atoms N0 = 5 x 1020 atoms. What is the power per unit area initially deposited by this source in a small target placed at 1m distance from the source? Select one: a. 35 W/m2 b. 1.45 W/m2 c. 4.5 kW/m2 d. 7.6 MW/m25. An XPS with an instrument work function of 4.5eV was used to analyze a surface. An observed kinetic energy of 795.2 eV was observed when a(n) MgKα (1253.6 eV) X-ray source was used. What was the binding energy of the electron coming from this surface?E1=164.4 meV Show all equations and values used
- question 4 pleaseAlpha particles of kinetic energy 6.9M V are incident at a rate of 3.1x 10" per second on a copper foil of thickness 3.1 x 10-m. A circular detector of diameter 1.0cm is placed 13cm from the foil at an angle of 30° with the direction of the incident alpha particles. At what rate does the detector measure scattered alpha particles? (The molar mass of copper is 63.5 and its density is 8.9em-)
