If you bombard Curium,
with alpha Helium.
You will gain Californium,
Actinoid, trans-Uranium.

Aritficial human made,
not easy to create.
First time in California achieved,
some appriciation received.

It was identified a second one,
in a twin birth they did come.
Berkelium is the twins name,
the city of the lab the very same.

Californium is pure radioactive energy,
millions of neutrons a minute it sets free,
It is used as a radiocative reaction staring source,
handle with care of course.

One gram needs a metric ton of shield material,
to protect the enviroment overall.
It is critical, but with a long life,
other new elements from it derive.

Artificial and dangerous, put to good use,
take care, protect science from abuse.
Such power can found futures paradise,
or is able to let devastation arise.
