Question

We need to solve what the unknown parent particle is given the following information:

The decay of this parent particle ends with a stable Ba-137 isotope. To attain this species, the parent particle first undergoes beta decay and then a subsequent gamma decay (this is the decay we measure in lab). Write a balanced equation for each of the two steps of this radioactive decay and figure out the identity of the parent particle.
