The Canadian Penning Trap mass spectrometer has made mass measurements of 33 neutron-rich nuclides provided by the new Californium Rare Isotope Breeder Upgrade facility at Argonne National Laboratory. The studied region includes the 132Sn double shell closure and ranges in Z from In to Cs, with Sn isotopes measured out to A=135, and the typical measurement(More)
Measurements were perforlned for the photodisintegration cross section of the deuteron for photon energies from 1.6 to 2.8 GeV and center-of-mass angles from 37" to 90". The measured energy dependence of the cross section at 8, , , = 90" is in agreement with the constituent counting rules. One of the rnost intriguing issues in nuclear physics is whether(More)
A measurement of the α-β-ν[over ¯] angular correlation in the Gamow-Teller decay (8)Li→(8)Be(*)+ν[over ¯]+β, (8)Be(*)→α+α has been performed using ions confined in a linear Paul trap surrounded by silicon detectors. The energy difference spectrum of the α particles emitted along and opposite the direction of the β particle is consistent with the standard(More)
Separated longitudinal and transverse cross sections for charged pion electroproduction from (1)H, (2)H, and (3)He were measured at Q(2) = 0.4 (GeV/c)(2) for two values of the invariant mass, W = 1.15 GeV and W = 1.60 GeV, in a search for a mass dependence which would signal the effect of nuclear pions. This is the first such study that includes recoil(More)
In the standard model, the weak interaction is formulated with a purely vector-axial-vector (V-A) structure. Without restriction on the chirality of the neutrino, the most general limits on tensor currents from nuclear β decay are dominated by a single measurement of the β-ν[over ¯] correlation in ^{6}He β decay dating back over a half century. In the(More)
The masses of exotic nuclei must be measured or calculated very precisely to explain how they led to the formation of heavy elements. If gold had been as abundant on earth as iron, it wouldn't be as famous for its rarity. If a tiny screw in the cosmic kitchen had been turned by just a bit, iron might have been the one that was most rare and desired, but(More)
We propose to extend our previous measurements of G n E from deuterium to Q 2 = 6.88 (GeV/c) 2. Additional measurements at 5.22, 3.95, and 2.18 (GeV/c) 2 will provide continuity with our prior measurements up to Q 2 = 1.45 (GeV/c) 2 , and overlap with recent (unpublished) measurements from a polarized 3 He target. The JLab E93-038 collaboration measured G n(More)
