Coulomb Potential Barrier: Is This Calc Right? What's fm?

Click For Summary
SUMMARY

The Coulomb potential barrier for two nuclei X and Y is accurately calculated using the formula VC = ZX*ZY*e2/RN, where ZX and ZY represent the charge numbers of the nuclei, and e2 is defined as 1.44 MeV*fm. The nuclear radius RN is computed as RN = (AX1/3 + AY1/3) × r0, with r0 typically estimated between 1.2 to 1.3 femtometers (fm). The term "fm" refers to femtometer, which is equivalent to 10^-15 meters. This calculation is confirmed to be correct based on the provided definitions and constants.

PREREQUISITES
  • Understanding of nuclear physics concepts, specifically Coulomb potential barriers.
  • Familiarity with the definitions of charge numbers (ZX, ZY) in nuclear interactions.
  • Knowledge of mass numbers (AX, AY) and their implications in nuclear calculations.
  • Basic mathematical skills to manipulate exponents and constants in equations.
NEXT STEPS

The Coulomb potential barrier of a system of two nuclei X and Y is approximately given by VC = ZX*ZY*e2/RN where ZX and ZY are the charge numbers of the nuclei, e2 = 1.44 MeV*fm, RN = (AX1/3+AY1/3) × r0 is the sum of the nuclear radii. r0 is a constant usually estimated to 1.2 to 1.3 fm and AX and AY are the mass numbers of the nuclei. Is this right calculation? What does fm stands for?

It looks rlight. fm stands for femtometer (10^-15 meter).
The AX1/3 sands for AX to the one third power.
