摘要：

The neutron-deficient isotopes Ti-39 and Ti-40 have been produced as fragments of Ni-58 projectiles at 65 MeV per nucleon. Decay by beta-delayed charged-particle emission has been observed for both of them with half-lives of 26(-7)+8ms for Ti-39 and 56(-12)+18ms for Ti-40. No evidence for direct two-proton emission from Ti-39 was obtained. The conditions that would make such a new radioactive mode possible are discussed.
