The 1/2+ ground state and a 11/2- isomer of very neutron-deficient isotope were produced by irradiation of an enriched target of with and studied by using a helium-jet fast tape-transport system in combination with proton- , X- and - coincidence measurements. A simple ( ) decay scheme of with a half-life of 3.0(3) s and a tentative ( ) decay scheme of with a half-life of 5.6(10) s are proposed. As a by-product, the 347- and 545-keV transitions in following the -delayed proton emission of decay and the 323-keV transition in following the -delayed proton emission of decay could be observed for the first time.
