1. Thank you very much for the implementation !!!
2. In Article Authors use
Exp(-beta R)/ R
However in the program they left beta also near R in denominator:
Exp(-beta R)/ (beta R)

Probably that should be corrected in the program.

Part of program:

RDIS = DSQRT(RR)*BETA
EXPR= DEXP(-RDIS)
TERM1 = CHARGE(JAT)/RDIS*EXPR*PI/2.0D0

I was using following command line:

REM compile
C:\gcc\bin\gfortran.exe -c adapyukdriver.f fmmadapyuk.f prini.f second.f treeadap.f yukadap.f yukoperators.f yuktable.f 
REM link
C:\gcc\bin\gfortran.exe -g adapyukdriver.o fmmadapyuk.o prini.o second.o treeadap.o yukadap.o yukoperators.o yuktable.o -o fmm.exe

As you see I am on windows
