Symmetries and Fundamental Interactions in Nuclei

View full text Add to dashboard Cite

Beta-decay and muon-capture experiments in nuclei are reviewed. The conserved vector current hypothesis is confirmed through the observed constancy of the vector coupling constant determined from the superallowed Fermi transitions and from the measurement of the weak-magnetism term in mirror Gamow-Teller transitions. The axial-vector and pseudoscalar coupling constants in the nucleon are determined from neutron decay and muon capture on the proton respectively. In finite nuclei, evidence for these coupling constants being reduced relative to their free-nucleon values is discussed. Meson-exchange currents are shown to be an important correction to the time-like part of the axial current as evident in first-forbidden beta decays. Tests of the Standard Model are discussed, as well as extensions beyond it involving right-hand currents and scalar interactions.Comment: 67 pages, plain LaTex, uses worldsci.sty, two figures embedded in manuscript as tex statements.

“…However the extraction of g p from nuclear radiative µ − capture measurements requires a model calculation of the inclusive nuclear response function and this piece of the determination is not yet under good control. For example the most precise measurement for the 16 O branching ratio [51] yields values of g p = 7.3 ± 0.9, 9.1 ± 0.9, and 13.6 ± 1.9 when compared with three different recent calculations of the nuclear response. Nevertheless there is a hint here that the value of g p in 16 O is larger than the PCAC value, Eq.…”

First-forbidden β decay: Meson-exchange enhancement of the axial charge atA∼16

1994

View full text Add to dashboard Cite

Calculations are presented for four relatively strong first-forbidden β decays in the region A=11-16 in order to study the very large mesonic-exchange-current enhancement of the rank-zero components. The µ − capture on 16 O is considered on the same footing. The wave functions utilized include up to 4hω excitations. Two-body exchange-current matrix elements are calculated as well as onebody impulse approximation matrix elements. The resultant enhancement factor that multiplies the impulse-approximation axial-charge matrix element is thereby determined by comparison to experiment to be ǫexp = 1.61 ± 0.03 from three β − decays and µ − capture on 16 O, which is in excellent agreement with meson-exchange calculations in the soft-pion approximation.
