Study of ${}^{123}$Ag β-decay at ALTO

The neutron rich ${}^{123}$Ag nucleus was populated via induced photofission of UC${}_x$ at the ALTO ISOL facility. Its β-decay properties were studied by means of detecting β-delayed γ and neutron activities. The measured half-life T${}_{1/2}$ = 0.350(20) s agreed with the earlier data; the β-delayed neutron emission branching P${}_{1n}$ = 1.01(24)% was reestablished using γ and neutron counting.
