N2 - A measurement of the photon asymmetry [Formula Presented] in radiative muon capture RMC on [Formula Presented] has been carried out at TRIUMF. Negative muons were stopped in a [Formula Presented] target and the resulting RMC photons were then converted by a 5-cm thick NaI detector placed immediately in front of our main NaI detector, a cylindrical crystal of diameter 46 cm and depth 51 cm. The data sample consisted of 5200 high-energy [Formula Presented] RMC photon candidates. Our measured value for the energy-averaged photon asymmetry is [Formula Presented] The extracted values for the induced pseudoscalar coupling constant [Formula Presented] based on this photon asymmetry measurement are [Formula Presented] utilizing the impulse approximation IA model, and [Formula Presented] in terms of the modified impulse approximation (MIA) model. The two extracted values, although both consistent with the Goldberger-Treiman value of [Formula Presented] are considerably different, indicating a significant theoretical model dependency.
