We consider two different models to explain the gamma-ray feature detected on Nova Muscae 1991: a thermal electron-positron plasma and α-α reactions. In the first case, a direct fit to the data using the detailed model spectrum developed by Svensson (1983ApJ...270..300S) gives a redshifted line (z=0.048^+0.017^_-0.027_) coming from a relatively low temperature pair plasma (T~4x10^7^K). In the second case, a Monte Carlo simulation of ^7^Be^*^-^7^Li^*^ de-excitation lines following Ramaty et al. (1979ApJS...40..487R) (RKL79 hereafter), gives a best fit model with monoenergetic and isotropic α particles of ~10-25 MeV/nucleon or power-law distributions of isotropic α particles with index of ~2 to 3.
