["LANNI, MARC" <MLANNI@entergy.com>]

The method on pgs 35 and 36 of NUREG/CR-5873 gives direction on adding the
nuclides you mentioned. When we added them to our file we used Mn-52 as the 
basis for the Mn-54 and Cr-51 as the basis for Sn-113. Values for Pi and Ei
were
taken from Erdtmann/Soyka Vol. 7. The value for u/p was obtained from pg 140

of the Radiological Health Handbook. Then we calculated the average Gamma
Energy
in Kev. The last two fields in the copied data were replaced with the
calculated
values XX90 numbers in the first line of data were retained as 0.001 to
disable
the Beta dose calculations.

We are trying to add a couple of nuclides to the VARSKIN MOD2 Betadata.dat
data base.  One of the parameters needed is the Degree of Forbiddenness for
that decay path.

We would appreciate any information that could be provided on how to either
find the appropriate data ( Mn-54 and Sn-113 ), or the appropriate method of
performing the calculation to obtain the needed parameter.

Thank you in advance for your time and consideration.
