Reasonable values for gamma:

gamma

float[dimensionless scalar variable]

The value used in the calculations is associated with the weight in the probability density function (weight $r_{ij}^{\delta \nu - 2}$ times an additional weight of $4 \pi r_{ij}^2 \Delta r$ for the volume). From Eq. (3), this is express in general as

$$p(r_{ij} )=C_{ij}^{\gamma \delta } \mathop {\left( {\frac{r_... ...c{r_{ij} }{b}} \right)}\nolimits^\delta } \right\}\Delta (r/b)$$ (93)

In this program, choices for $\gamma$ should range between $0.3 < \gamma < 4.0$, where reasonable values are probably somewhere in the middle and for Flory theory, the default is $\gamma \equiv 1$. I originally defined $\gamma$ in terms of the Gaussian functions. Now the equations look more appealing, but the meaning of $\gamma$ as a self avoiding weight is somewhat a matter of question. In the McKenzie-Moore-Domb-Fisher model, $\delta$ can be any value and their parameter $t$ has some appeal because it is simply the additional contribution of the distribution function to the Gaussian situation. The relationship between $t$ and $\gamma$ is as follows: $t + 2 = \delta \gamma$ or $\gamma = (t + 2)/\delta$.
