Valence proton vacancy of the Si ground state
N. Watwood, C. R. Hoffman, B. P. Kay +22
The Si(He,)P reaction was studied in inverse kinematics at 6.3~MeV/. States in P corresponding to the proton single-particle orbitals were id…
Near-threshold dipole strength in {^{10}}Be with isoscalar character
J. Chen, Y. Ayyad, D. Bazin +29
Isoscalar dipole transitions are a distinctive fingerprint of cluster structures. A {1^-} resonance at 7.27(10) MeV, located just below the α-emission threshold, has been observed…
Meaurement of spin vs. TKE of Ba produced in spontaneous fission of Cf
N. P. Giha, S. Marin, I. A. Tolstukhin +21
We measure the average spin of Ba, a common fragment produced in Cf(sf), as a function of the total kinetic energy (TKE). We combined for the first time a twin Fris…
Gamow-Teller strengths from unstable O via the reaction in inverse kinematics
S. Giraud, J. C. Zamora, R. Zegers +24
For the first time, the reaction was successfully used in inverse kinematics to extract the Gamow-Teller transition strength in the direction from an un…
Evidence of a near-threshold resonance in B relevant to the -delayed proton emission of Be
Y. Ayyad, W. Mittig, T. Tang +27
A narrow near-threshold proton-emitting resonance (Ex = 11.4 MeV, J = 1/2 and = 4.4 keV) was directly observed in B via proton resonance scattering. This r…
Beam Particle Identification and Tagging of Incompletely Stripped Heavy Beams with HEIST
A. K. Anthony, C. Y. Niu, R. S. Wang +26
A challenge preventing successful inverse kinematics measurements with heavy nuclei that are not fully stripped is identifying and tagging the beam particles. For this purpose, the…
Beam induced space-charge effects in Time Projection Chambers in low-energy nuclear physics experiments
J. S. Randhawa, M. Cortesi, Y. Ayyad +14
Tracking capabilities in Time Projection Chambers (TPCs) are strongly dictated by the homogeneity of the drift field. Ion back-flow in various gas detectors, mainly induced by the…
Direct observation of proton emission in 11Be
Y. Ayyad, B. Olaizola, W. Mittig +30
The elusive decay was observed in Be by directly measuring the emitted protons and their energy distribution for the first time with the prototype Active Tar…
