19F (p, alpha gamma) 16O reaction: HPGe detector response function and gamma-ray relative yields (2007)

Tridapalli, D. B., Pascholati, P. R., Maidana, N. L., Vanin, V. R., Guimarães-Filho, Z. O., Rizzutto, M. A.

The 6.1, 6.9 and 7.1 MeV photon yields in the reaction with protons in the 1.32 to 1.42 MeV energy range were determined from the comparison between experimental and simulated spectrum. The gamma-ray...
