On the 7Be* and 7Li* de-excitation lines as a possible explanation of the gamma-ray feature observed in Nova Muscae1991.

Abstract (from CDS):
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∼4x107K). In the second case, a Monte Carlo simulation of 7Be*-7Li* 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.
