Isomeric state of 80Y and its role in the astrophysical rp-process (2008)

Novikov, Yu.N., Schatz, H., Dendooven, P., Béraud, R., Miehé, Ch., Popov, A.V., ...

Revised rates for the stellar triple-alpha process from measurement of C-12 nuclear resonances (2008)

Fynbo, H.O.U., Diget, C.A., Bergmann, U.C., García Borge, María José, Cederkäll, J., Dendooven, P., ...

In the centres of stars where the temperature is high enough, three alpha-particles (helium nuclei) are able to combine to form C-12 because of a resonant reaction leading to a nuclear excited...

Precise half-life measurement of the 26Si ground state (2008)
