Calcular ( E_F ) para un metal con ( n ) electrones/volumen.
Fórmula: ( E_F = \frac\hbar^22m (3\pi^2 n)^2/3 ).
Older wrong versions had (\sin^2(\alpha a)) or (\sin^2(k a)) – that’s the error. If you see sine instead of hyperbolic sine, you have the unfixed version. Conceptos clave:

While I do not endorse piracy, students often use the exact keyword:
"solucionario de curso de fisica moderna virgilio acosta 320 fixed"
on Google, DuckDuckGo, or in Telegram channels. You may find a *.rar or *.pdf file. If you do, verify problem 320 by comparing the formula for the potential barrier. The “fixed” version will have (\sinh^2(\alpha a)) in the denominator, not (\sin^2(k a)).
Warning: Many “fixed” versions still have errors. Some change the problem number incorrectly. Others fix the algebra but introduce a numerical mistake for the electron mass or ℏ value. Ejercicio común: Calcular ( E_F ) para un
