Precision half-life measurement of ²⁹P

RADIOACTIVITY ²⁹P(β⁺)[from ²H(²⁸Si, X), E=9 MeV, followed by separation of ²⁹P using the TwinSol facility at the FN tandem accelerator of the University of Notre Dame, and implantation of ²⁹P beam in the NSL β-decay counting station]; measured β spectra, precise half-life of the decay of ²⁹P; deduced ft value for the β transition to the ground state of ²⁹Si, Cabibbo-Kobayashi-Maskawa matrix element V_ud, Fermi to Gamow-Teller mixing ratio; evaluated half-life using present and previous experimental values. Discussed in detail corrections and uncertainties. Comparison with previous half-life measurements.

Dominance of direct reaction channels at deep sub-barrier energies for weakly bound nuclei on heavy targets: The case ⁸B + ²⁰⁸Pb

NUCLEAR REACTIONS ²⁰⁸Pb(⁸B, ⁷Be), E=30 MeV, [secondary ⁸B beam from ³He(⁶Li, X)⁷Li/⁷Be/⁸B reaction using TwinSol facility at the University of Notre Dame FM tandem accelerator]; measured reaction products and elastically scattered particles, differential σ(θ) using Si telescopes, time-of-flight ΔE-E spectra; deduced direct to total reaction cross section, and compared with previous experimental σ ratios for ²⁰⁹Bi+⁶He, ⁵⁸Ni+⁸B, and ²⁸Si+⁷Be reactions, breakup cross section for the ²⁰⁸Pb+⁸B system at deep sub-barrier energies. Comparison with CDCC calculations, with Coulomb plus nuclear potentials, and Coulomb potentials only.
