In a first application of the gamma-ray-induced Doppler broadening technique to a heavy mass nucleus the first absolute transition rates from a {sigma}{lt}{ital N} state in an O(6) nucleus ({sup 196}Pt) are obtained. The principal results concerns the 1402 keV 0{sup +} base state of the {sigma}={ital N}{minus}2 family, namely, that {ital B}({ital E}2:(0{sub 3}{sup +}({sigma}=4)-2{sub 1}{sup +}({sigma}=6))){lt}0.034 {ital e}{sup 2} b{sup 2}. In agreement with the selection rule which forbids {Delta}{sigma}=2 transitions, this corresponds to at least an order-of-magnitude hindrance compared to allowed O(6) transitions and provides a critical test of the {sigma} quantum number.
