1979Sc09: 215Pa activity was produced with 181Ta(40Ar,6n), E=165-202 MeV and separated with a velocity filter. The activity was identified by excitation functions, and by its genetic relationship to daughter nuclei. Measured Eα, α(t).
2000He17 (also 1996An21): 215Pa activity produced with 170Er(51V,6n), E=214-286 MeV and separated from the beam with a velocity filter. The activity was identified by its genetic relationship to daughter nuclei. Measured Eα, α(t) with 16-strip Si detector.
2018Ya01: 215Pa activity produced as daughter of 219Np. Alpha decays from 215Pa could not be distinguished from those of 214Pa.
Q-value: S(2n)=17990 100, S(2p)=2910 80, Q(εp)=4080 80 (2021Wa16)
