DOIAbstract
Fusion-evaporation reactions with the doubly magic projectile Ca-48 were used to access neutron-deficient nuclei around neptunium at the velocity filter SHIP, and investigated using the COMPASS decay spectroscopy station. With the use of digital electronics, several isotopes produced via neutron, proton, and a evaporation channels were identified by establishing correlated alpha-decay chains with short-lived sub-s, members. Data are given on decay chains stemming from Np-225,Np-226 U-225, and Pa-222,Pa-223. New information on the isotopes Np-225,Np-226 and Pa-222 was obtained. Production cross sections of nuclei in the region using a variety of projectiles are discussed. The measured production cross-sections indicate that the usual advanta...
