Nuclear Magnetic Resonance Measurements of the Isotopes Barium-135 and Barium-137

135Ba and137Ba Fourier transform NMR and NQR studies

“…The NQR-frequencies are within the frequency range of the spectrometer. [16]. The ratio for ~35Ba and 35C1 given above agrees with the results of [16] if the different samples are taken into account.…”

“…Since there exist only few NMR (Ref. [16][17][18][19] and NQR (Ref. [19][20][21][22] results in solids and solutions measurements and calculations of the following quantities are important: ratio of the Larmor frequencies of the barium nuclei to that of a standard nucleus, nuclear magnetic moments, chemical shifts, shielding constants, linewidths and relaxation rates in aqueous and non-aqueous solutions, ratios of the quadrupole frequencies and quadrupole moments, NMR signals at low concentrations and natural abundance.…”

High resolution spectroscopy of the transition 5d2D3/2?6p2P 3 2/0 in a fast Ba+ ion beam

“…Therefore we were not able to measure hfs anomalies in the A-factors or to improve the value for the ratio of the quadrupole moments. The values for the A-and B-factors of 13SBa given in Table i were derived from both the 135Ba and the 137Ba hfs recordings using the known ratios 137gi/135g I = 1.11868 [12] and 137Q/135Q= 1.543 [13]. The P3/2-level splitting factors are compared with the results of Kraus and Andr~i obtained from quantum beat experiments [10] and results of Becker etal.…”
