Abstract: The present invention is a target for neutron generation, including a substrate coated with a palladium layer and a lithium layer such that a surface of the lithium layer is irradiated with charged particles to generate neutrons, and further including, between the palladium layer and the lithium layer, a barrier layer made of a metal that does not form a eutectic alloy with either palladium or lithium. As constituent metals for the barrier layer, specifically, copper, iron, nickel, cobalt, titanium, and zirconium are preferable. The target for neutron generation of the present invention does not degrade in performance even through long-term operation, and can also prevent lithium layer separation.

Abstract: The present invention is a precious metal-based amorphous alloy having a Pt—Cu—P based structure including in atomic %: 50≦Pt≦75%, 5≦Cu≦35%, and 15≦P≦25% and is a precious metal-based amorphous alloy having a Pt—Pd—Cu—P based structure including in atomi %: 5≦Pt≦70%, 5≦Pd≦50%, 5≦Cu≦50%, and 5≦P≦30%. Preferably, cooling rates for manufacturing the alloys having these compositions are 10−1 to 102° C./sec. for the Pt—Cu—P based structure and 101 to 102° C./sec. for the Pt—Pd—Cu—P based structure.
