Assertion: gamma ray's source | /r/CapableOf | produce gamma-ray line spectra
Facets:
value: typically
type: DEGREE
Source sentences:
text: Such sources typically produce gamma-ray "line spectra" (i.e., many photons emitted at discrete energies), whereas much higher energies (upwards of 1 TeV) may occur in the continuum spectra observed in astrophysics and elementary particle physics.
