8. This approximation avoids mathematical intractability, and in a first-order approximation, is as acceptable as the one used for δE(t) calculation. This is due to the fact that interchain separation differs only in a molecular diameter from that used to obtain eq. (4). This assumption is validated by numerical trials.
