In this paper, the implantation-decay method is introduced to study the β-delayed charged particle decay. A silicon detector array was used for the implantation of the incident beams and for the detection of the emitted particles. An experimental measurement on the b-delayed particle emission from 22Al was used to demonstrate the method. The half-life value, charged particle spectroscopy, γ ray spectrum, and γ particle coincidence for the decay process were obtained and compared with previous experimental results for 22Al. The results show that the implantation-decay method, using a silicon detector array, is a suitable experimental method to study the β-delayed charged particle decay for proton-rich nuclei.

Key words: Implantation-decay method, β-Delayed proton emission, Proton-rich nuclei, 22Al
