We aim to determine the cross section for absorbing resonant radiation in rubidium atoms and to verify the nuclear spin of the two isotopes of Rubidium using optical pumping. The cross section determined by varying the temperature of a sample of rubidium vapour and measuring transmitted light intensity. While the nuclear spins are determined by exploiting the Zeeman effect and observing transition peaks.
