Prompt proton decay in the vicinity of 56Ni

A new decay mode, the so called prompt proton decay, was discovered in 1998. It has since proven to be an important decay mechanism for several neutron deficient nuclei in the A∼60 region. To measure with high accuracy the energies and angular distributions of these protons, a state-of-the-art charged particle detector--LuWuSiA--was developed. It was first utilized during a fusion-evaporation reaction experiment performed at Argonne National Laboratory, U.S.A. In this contribution, the characteristics of the prompt proton decay are discussed along with the special features of LuWuSiA as well as a revisit to the prompt proton decay in 58Cu
