Phys. Rev. C 65, 044618 (2002) [8 pages]Direct mass measurements of proton-rich isotopes of Ge, As, Se, and BrReceived 30 November 2001; published 3 April 2002 The masses of neutron-deficient nuclei close to the proton drip line are an important input for the rapid proton-capture process modeling above 56Ni. The measurement of the masses of proton-rich nuclei with 32<~Z<~35 has been made using a direct time-of-flight technique. The masses of the nuclides 66As,68Se, and 71Br are reported for the first time, with mass excesses of -51500(680), -53620(1000), and -57060(570) keV being found. The masses agree well in most cases with the Audi-Wapstra systematics. © 2002 The American Physical Society URL:
