Figure 4-26 shows an energy loss spectrum for He measured in an apparatus such as that shown
Question:
Figure 4-26 shows an energy loss spectrum for He measured in an apparatus such as that shown in Figure 4-24a. Use the spectrum to construct and draw carefully to scale an energy-level diagram for He.
Figure 4-24(a)
Transcribed Image Text:
FIGURE 4-26 Energy-loss spectrum of helium. Incident electron energy was 34 eV. The elastically scattered electrons cause the peak at 0 eV. Relative intensity 0 20.61 19.82 10 Energy loss, eV 20 21.21 23.07

As I'm a Ph.D. student, so I'm more focussed on my chemistry laboratory. I have qualified two national level exams viz, GATE, and NET JRF (Rank 68). So I'm highly qualified in chemistry subject. Also, I have two years of teaching experience in this subject, which includes college teacher as well as a personal tutor. I can assure you if you hire me on this particular subject, you are never going to regret it.
Best Regards.
