متن کاملUnderstanding the 11B(p,α)αα reaction at the 0.675 MeV resonance
a r t i c l e i n f o a b s t r a c t The 11 B(p, α)αα reaction at energies between 200 keV and a few MeV has a very long history, dating back to studies by Lord Rutherford and Dee and Gilbert in the 1930s. It is shown that the modern view of this reaction, established in 1987, is incorrect. This model viewed the reaction as a two-step process with a primary high energy α-particle having = 1 go...
متن کاملα decay of the excited states in 12 C at 7 . 65 and 9 . 64 MeV
High-resolution triple-α coincidence data were used to reconstruct the decay of the excited states in 12C at 7.65 MeV (J π = 0+) and 9.64 MeV (J π = 3−). These data are consistent with the α-particle decay of both levels proceeding exclusively through Beg.s.. In the first of these cases, the Hoyle state, an upper limit of 0.45% (at the 99.75% confidence level) is set for a component producing t...
متن کاملRoper excitation in ⃗p + α → ⃗p + α + X reactions
We calculate differential cross sections and the spin transfer coefficient D nn in the p+α → p+α+π 0 reaction for proton bombarding energies from 1 to 10 GeV and π 0 − p invariant masses spanning the region of the N * (1440) Roper resonance. Two processes – ∆ excitation in the α-particle and Roper excitation in the proton – are included in an effective reaction model which was shown previously ...
