The Energy Returned on Invested, EROI, has been evaluated for typical power plants representing wind energy, photovoltaics, solar thermal, hydro, natural gas, biogas, coal and nuclear power. The strict exergy concept with no ”primary energy weighting”, updated material databases, and updated technical procedures make it possible to directly compare the(More)
– To study the electron screening of nuclear reactions in metallic environments, angular distributions and thick target yields of the fusion reactions H(d,p)H and H(d,n)He have been measured on deuterons implanted in three different metal targets (Al, Zr and Ta) for beam energies ranging from 5 to 60 keV. The experimentally determined values of the(More)
TACTIC is a new detector for low energy nuclear reactions currently under development at TRIUMF. The cylindrical ionization chamber allows three-dimensional reconstruction of particle tracks by means of a two-dimensional anode array combined with a TOF measurement of the drift electrons. In addition, the integrated charge for each pulse provides information(More)
The reaction threshold for deuteron induced reactions on B amounts to 25.2 MeV, which enables an excitation of the giant resonances (GR) in the compound nucleus C even at very low projectile energies. In our recent experimental and theoretical investigations of the B(d,p)B reaction, we have found a strong reaction contribution arising from the giant dipole(More)
The p((11)Li, (9)Li)t reaction has been studied for the first time at an incident energy of 3A MeV at the new ISAC-2 facility at TRIUMF. An active target detector MAYA, built at GANIL, was used for the measurement. The differential cross sections have been determined for transitions to the (9)Li ground and first excited states in a wide range of scattering(More)

The strength of the Ec.m. = 184 keV resonance in the 26gAl(p, gamma)27 reaction has been measured in inverse kinematics using the DRAGON recoil separator at TRIUMF's ISAC facility. We measure a value of omega gamma = 35 +/- 7 microeV and a resonance energy of Ec.m. = 184 +/- 1 keV, consistent with p-wave proton capture into the 7652(3) keV state in 27Si,(More)
