## 5. A semi-analytical relation between andOur aim is to find a semi-analytical relation
for the intervals and
. with: The value of the correlation coefficient between this function and the numerical integration is . With this method we find for several values of inside the interval . We can write the dimensionless collapse time as the product: where the function can be written as and, for and ,
A test performed between the values
obtained for from the numerical integration and
the values obtained from Eq. (7) gives the result:
