Isoscaler and isovector for one body of magnetic dipole transitions of Ba(A=130- 136) isotopes using IBM-1

Abstract

l

 

Isoscalar   and  isovector   for  one   body  of  magnetic   dipole transitions    of   even even   Ba   (A=l30-136)  isotopes   have   been calculated using IBM-1 . The present calculations are predicted that the maximum   values    of   magnetic    dipole   reduced   matrix   clement (11  II fr.·Hil lll1         were  found   in  Ba  (A=I30   and  A=136)   for  the

transitions  3!3j   and  42   4jwhile   the  minimum values in the

tr_ansitions  2; 2; and  4! -74; for Ba=l30 and for Ba(A=132  and for Ba(A= 132 and A=I34)  at the transitions of  22!i- The va_.lues

• ofreduced matrix  element  (I1 .II f (MI) !I li ) in Ba=l36 were appeared

-after the separation  of proton bosons. and neutron bosons at  zt ,3t'

4i and 5    states.. These values were equal to (2.293---.-1.356) IJ.n for

isovector  operators.  The  values  of  B(Ml) doesn't  appears  be.cause there  are  no  transition:s   between  these  energy  states  other  energy states.
