“…The beam-pulse repetition-rate was 4 MHz. The neutron spectr-um incident on a capture sample was measured by means of a time-of-flight (TOF) method with a 5.0-mm diameter and 5.0-mm thick 6 Liglass scintillation detector located 30 cm from the neutron source. The angle between the detector axis and the proton-beam direction was adjusted to 14 °.…”

The capture 'Y rays from the broad 53-keV and the narrow 35-keV p-wave neutron resonances of 23 Na were measured using a large anti-Compton HPGe "(-ray spectrometer. A neutron time-of-flight method was adopted with a 1.5-ns wide pulsed-neutron source by the 7 Li(p, n)7Be reaction. The standard capture cross sections of 197 Au and a pulse-height weighting technique were employed to det~rmine the number of neutrons incident on a capture sample. The numbers of observed primary "(-ray transitions were 15 and 13 for the 53-and 35-ke V resonances, respectively. The partial capture kernels and the partial radiative widths corresponding to these transitions were derived for the first time. The total radiative widths of these resonances were also derived. The present results are compared with measurements by other authors and evaluations. Moreover, a new 4,909-keV state in 24 Na was found and its spin and branching ratio were determined from the analysis of the "(-ray transitions from the narrow 35-keV resonance.
