Answer:

Promethium-147 changes into promethium-148.

Explanation:

Beta-decay: In this process, a neutron gets converted into a proton and an electron releasing a beta-particle. The beta particle released carries a charge of -1 units.

$_Z^A\textrm{X}\rightarrow _{Z+1}^A\textrm{Y}+_{-1}^0\beta$

$_{147}^{61}\textrm{Pm}\rightarrow _{148}^{61}\textrm{Pm}+_{-1}^0\beta$

During beta decay promethium-147 changes to promethium-148.
