Compilations of experimental E1 and M1 strength functions
(original file provided by J. Kopecky to RIPL-1)
(reformatted by M. Herman on November 19, 2001)

Content
-------
Compilations of experimental E1 and M1 strength functions (fE1 and fM1) for
nuclei from F-20 up to U-239. In certain number of cases the original values
were corrected (typically for nonstatistical effects). Therefore,the table
contains both original and recommended values in units of [10**(-8) MeV**(-3)].
Format
------
Each record of the file contains:
Z : atomic number
A : mass number (0 stands for natural element)
El : element symbol
Reac Key: 1 for (n,g), 2 for (g,n), 3 for (n,g) at thermal energy
Eg(E1) : mean energy of E1 transitions
fE1 : recommended gamma-ray strength function f(E1) based on
s-(p-)wave neutron capture and photonuclear data
Err : recommended uncertainty (quadrature added statistical
normalization (20%) and Porter-Thomas uncertainty)
fE1 : original gamma-ray strength function f(E1) based on
s-(p-)wave neutron capture and photonuclear data
Err : original uncertainty (quadrature added statistical
normalization (20%) and Porter-Thomas uncertainty)
Eg(M1) : mean energy of M1 transitions
fM1 : recommended gamma-ray strength function f(M1) based on
s-(p-)wave neutron capture and photonuclear data
Err : recommended uncertainty (quadrature added statistical
normalization (20%) and Porter-Thomas uncertainty)
fM1 : original gamma-ray strength function f(M1) based on
s-(p-)wave neutron capture and photonuclear data
Err : original uncertainty (quadrature added statistical
normalization (20%) and Porter-Thomas uncertainty)
Ref : reference number (see list below)
The corresponding FORTRAN format is (2I4,1X,A2,I3,10F6.3,I4)
