The radiative lifetime Trad of the CH2(g 'BI) state has been determined using the CHz(g 'Bl +y lAl) emission produced by electrons incident on CH4. The value found for Trad is 1.90(%0.15) X lo\* s. A second lifetime component, 8.5(\* 1.0) X LO\* S, has been measured which is related to either cascad
