First measurement of the $^{34}\mathrm{S}(p,{\gamma})^{35}\mathrm{Cl}$ reaction rate through indirect methods for presolar nova grains
Résumé
Sulphur isotopic ratio measurements may help to establish the astrophysical sites in which certain presolar grains were formed. Nova model predictions of the S34/S32 ratio are, however, unreliable due to the lack of an experimental S34(p,γ)Cl35 reaction rate. To this end, we have measured the S34(He3,d)Cl35 reaction at 20 MeV using a high resolution quadrupole-dipole-dipole-dipole magnetic spectrograph. Twenty-two levels over 6.2 MeV
