6. (30 points) Construct the energy level diagram for a singly ionized helium (Z = 2) up to the first six energy levels. Show proper energy in eV for each level. П n Anode Photoelectrons Metal specimen (a) An electron in a helium atom jumps from some initial orbit ni to some final orbit nf. If the photon emitted in the process is capable of ejecting photoelectrons from a metal specimen (work function 7.00 eV), determine nf. = (b) If a minimum stopping potential of Vo = 5.09 V is required to prevent the photoelectrons from hitting the anode, determine the value of ni.
