 I ran rdecay01 with attached macro. here is the result. 
 Al26 isomer decays as expected ...

 ======================== run summary ======================
 The run was 100000 Al26[229.0] of 0 eV
 ===========================================================

 Nb of generated particles:

    Al26[229.0]:  100000  Emean =      0 eV     ( 0 eV  --> 0 eV )
      Mg26[0.0]:  100000  Emean =    156 eV     ( 0.06561 eV  --> 370.1 eV )
             e+:   99937  Emean =  1.413 MeV    ( 207.1 eV  --> 3.176 MeV)
           nu_e:  100000  Emean =  1.798 MeV    ( 34.12 keV --> 4.232 MeV)

   Ekin Total (Q): mean =  3.211 MeV    ( 3.21 MeV --> 4.232 MeV)

   Momentum balance (excluding gamma desexcitation): mean = 5.715e-06 eV        ( 9.395e-11 eV  --> 0.0002179 eV )

   Total time of life : mean =  9.187 s    half-life =  6.368 s     ( 55.6 mus --> 1.845 min)

   Activity of Al26[229.0] = 2.521e+21 Bq/g   (6.814e+10 Ci/g)
