centrifugal barrier

centrifugal barrier

[‚sen′trif·i·gəl ′bar·ē·ər]
(mechanics)
A steep rise, located around the center of force, in the effective potential governing the radial motion of a particle of nonvanishing angular momentum in a central force field, which results from the centrifugal force and prevents the particle from reaching the center of force, or causes its Schrödinger wave function to vanish there in a quantum-mechanical system.

They are bound dynamically by the centrifugal barrier between the atoms, which make it spin around its parent nucleus for a tad bit longer than necessary.
2] as k [right arrow] 0, independent of the shape of the potential because the centrifugal barrier inhibits penetration of the wavefunction into the region of interest, as seen in Fig.
If we ignore the hyperfine contribution in the multi-channel f = 1 and f = 2 Hamiltonians the sole difference between the two Hamiltonians is the centrifugal barrier e(e+ l)/2[micro][R.
