Production of the light elements lithium, beryllium, and boron by proton-induced spallation of 14N

Astrophysically interesting cross sections for the production of isotopes of lithium, beryllium, and boron in the proton-induced spallation of ¹⁴N were measured for proton energies between 17 and 42 MeV. A time-of-flight method was used for mass identification, supplemented at one energy by radioactivity analysis. Gas targets were used throughout. The astrophysical significance of the results is discussed.
