Determine the transmission coefficient for an electron

Click For Summary
SUMMARY

The discussion revolves around calculating the transmission coefficient for an electron, specifically addressing discrepancies between a user's calculated value of 0.016 and the book's value of 0.963x10^-38. The user initially struggled with the formula provided in the textbook but later resolved the issue independently. This highlights the importance of careful calculation and understanding of the underlying physics principles involved in quantum mechanics.

PREREQUISITES
  • Quantum mechanics fundamentals
  • Understanding of wave-particle duality
  • Familiarity with transmission coefficients
  • Proficiency in using scientific calculators for complex equations
NEXT STEPS

I have an example problem in my book. I have uploaded an image. The part I can't figure out is how to do the last part of the problem to come up with the transmission coefficient. The book gives me a formula but when I plug in all the numbers from the formula into my calculator I get a completely different answer than the book. The number I get is roughly 0.016 where as the book gets 0.963x10^-38. That is way different than what I'm getting and I'm not sure why. Any help would be awesome.
