Prompt γ-ray spectroscopy of the neutron-rich 124Cd

EPJ Web of Conferences, 2013
Prompt γ-ray spectroscopy of neutron-rich cadmium isotopes has been performed. The nuclei of interest have been populated via a 25-MeV, proton-induced fission of the 238U thick target and prompt γ-rays measured using the multi-detector HPGe array JUROGAM

Investigation of the reaction 90Zr(p,γ) with in-beam γ-ray spectroscopy

EPJ Web of Conferences, 2015
The p nucleus 92Mo is believed to be mainly produced through photodisintegration reactions in type II supernovae. However, this production scenario cannot solely account for the observed solar relative isotopic abundance of 92Mo.
