Content
-------
The Table contains 328 experimental deformation parameters beta2 derived from 
the  model-independent experimental values of the reduced electric quadrupole
transition  probability B(E2).  Assuming a uniform charge distribution out to
the distance R and zero charge beyond, the model-dependent deformation
parameter beta2 is  related to B(E2) by (Eq.2 of Raman et al. 1987)
   
   beta2=(4pi/3ZR0^2) [B(E2)/e^2]^2

where R0=1.2 A^(1/3).


Format
------
Each record of the file contains:

   Z    : charge number
   A    : mass number
   El   : element symbol
   beta2: experimental deformation parameter
   error: estimated error on the experimental deformation parameter

The corresponding FORTRAN format is (2i4,1x,a2,1x,2f8.4)
