An explanatory study of $^{11}$Li $\beta$ decay into $^9$Li and deuteron
  The $\beta$-decay of $^{11}$Li into $^9$Li and {\it d} is studied using simple halo wave functions of $^{11}$Li.   The sensitivity of the transition probability is elucidated on a description of the halo part and on a choice of the potential between $^9$Li and {\it d} .
