Gross collision model susceptibility

We employ the Gross collision model for which this susceptibility xor[z(v)] is related to the correlator ( spectral function ) Lor of the hat model as... [Pg.338]

Second, the SF (254) is used in the case of the Gross collision model as a constitutive element of the formula for the complex susceptibility Xg I 1 this case the orientational distribution Fq, differing from FB, changes radically the calculated low-frequency spectrum, while the far-IR spectrum is very close to that given by the Boltzmann susceptibility Xb (252). We shall return to this point in Section IX.D. [Pg.498]

For other collision models (e.g., for the Gross model, see GT1) the susceptibility % is related to the spectral function by a rational relation different from (83). This leads to an essential change of the low-frequency spectrum. [Pg.433]
