First isomeric yield ratio measurements by direct ion counting and implications for the angular momentum of the primary fission fragments

2018

We report the first experimental determination of independent isomeric yield ratios using direct ion counting with a Penning trap, which offered such a high resolution in mass that isomeric states could be separated. The measurements were performed at the Ion Guide Isotope Separator On-Line (IGISOL) facility at the University of Jyvaskyla. The isomer production ratios of Ge-81, Y-96,Y-97 Sn-128(,1)30, and Sb-129 in the 25-MeV proton-induced fission of U-na(t) and Th-232 were studied. Three isomeric pairs (Ge-81, Y-96, and Sb-129) were measured for the first time for the U-na(t)(p, f) reaction, while all the reported yield ratios for the Th-232(p, f) reaction were determined for the first ti…

MANUAL AND MECHANICAL LEAF REMOVAL IN THE BUNCH ZONE (VITIS VINIFERA L. 'NERO D'AVOLA'): EFFECTS ON PLANT PHYSIOLOGY, VEGETATIVE PARAMETERS, YIELD AN…

2013

Mechanical and manual leaf removal of Nero d Avola vines were carried out in a commercial vineyard in Sclafani Bagni area, Sicily (South Italy), in the 2007 growing season. Rows were North East-South West oriented and vines were spur pruned and non-irrigated. The aim was to investigate the effects of two different ways of defoliation on plant physiology, vegetative parameters, yield and grape quality in a warm temperature area. Fruit zone defoliation consisted of mechanical (MLR) and hand leaf removal (HLR), applied either to both sides of the canopy (Northweast and Southeast). These treatments were applied when the berries had reached pea size and compared to a non-defoliated treatment (co…

Production ofΛ0,Λ¯0,Ξ±, andΩ±hyperons inpp¯collisions ats=1.96  TeV

2012

We report a set of measurements of inclusive invariant ${p}_{T}$ differential cross sections of ${\ensuremath{\Lambda}}^{0}$, ${\overline{\ensuremath{\Lambda}}}^{0}$, ${\ensuremath{\Xi}}^{\ifmmode\pm\else\textpm\fi{}}$, and ${\ensuremath{\Omega}}^{\ifmmode\pm\else\textpm\fi{}}$ hyperons reconstructed in the central region with pseudorapidity $|\ensuremath{\eta}|l1$ and ${p}_{T}$ up to $10\text{ }\text{ }\mathrm{GeV}/c$. Events are collected with a minimum-bias trigger in $p\overline{p}$ collisions at a center-of-mass energy of 1.96 TeV using the CDF II detector at the Tevatron Collider. As ${p}_{T}$ increases, the slopes of the differential cross sections of the three particles are similar,…

Nuclear Modification ofψ′,χc, andJ/ψProduction ind+AuCollisions atsNN=200  GeV

2013

We present results for three charmonia states (psi' chi(c), and J/ psi) in d + Au collisions at vertical bar y vertical bar < 0.35 and root s(NN) = 200 GeV. We find that the modification of the psi' yield relative to that of the J/ psi scales approximately with charged particle multiplicity at midrapidity across p + A, d + Au, and A + A results from the Super Proton Synchrotron and the Relativistic Heavy Ion Collider. In large-impact-parameter collisions we observe a similar suppression for the psi' and J/ psi, while in small-impact-parameter collisions the more weakly bound psi' is more strongly suppressed. Owing to the short time spent traversing the Au nucleus, the larger psi' suppressio…
