Polarized B-12 nuclei were produced and recoil implanted in single crystals of fcc aluminum. The boron decay asymmetry and relaxation times were measured as a function of external magnetic field values and at different orientation angles of the cryst

We have remeasured the Korringa contributionT1e to the nuclear spin lattice relaxation time of the interstitial12B in nobel metals and in Al. TheT1eT times the squared Knight shiftK of12B taken from the literature, that is the Korringa product of12B,

The observation with high-resolution Ge detectors of the 1229 and 2171 keV gamma-rays emitted after the 28Si(μ, ν)28Al(1+, 2202 keV) reaction allowed us to determine the nuclear-amplitude ratio x ≡ M(2) M(−1) characteristic of this muon-capture

A magnetic field dependent version of the all-or-nothing model of Bloembergen and Rowland is proposed as a working hypothesis for the interpretation of the low field “decoupling-curve” in Rh metal. Further experiments are proposed to check up the

It is shown that /sup 12/B nuclei produced in the /sup 12 /C(/b n/ oarr ,/b p/)/sup 12/B reaction are polarized. The polarization of /sup 12/B is measured through its beta-decay asymmetry. The analyzing `efficiency' epsiv =/b P//sub N///b P //sub n/

Knight shift data of implanted 12B are used to estimate hyperfine field, Hhf(s), and Knight's ξ factor for Al, Cu, Ag, and Au metals at the boron site. In the Rh, Pd, and Pt transition metals the Knight shift and the Korringa relaxation time T1e are

The polarizations, P/sub av/equivalent/J and P/sub L/equivalent/J, of the /sup 12/B in the reaction /sup 12/C( ..mu../sup -/,..nu..)/sup 12/B(g.s.) have been measured simultaneously, using the method of selective recoil implantation. Their ratio R/su

A novel method involving the Zeeman effect is used to directly measure the alignment correlation term in the beta decay of /sup 12/B, /sup 12/B rarr beta +/sup 12/C. The approach is reminiscent of the direct measurements of the lepton g-factor anomal

An experiment to measure the rate lambda /sub beta / of the weak decay /sup 16/N/sup m/(O/sup -/, 120 keV) rarr /sup 16/O(O/sup +/, g.s.)+ beta /sup -/+ nu macr is described. The results are combined with the rate lambda /sub mu / for the inverse rea
