“…This value is in agreement with the value of 2.9 + 0.1 MeV reported by Lycklama, £l_. (34). The decay scheme used in selecting the gating gamma-ray transitions and in deter mining percent beta feeding to the various daughter energy levels was determined by R. L. Bunting (3S).…”

“…The results of the analysis of the beta-ray spectra for the eleven nuclei studied are reported in Tables 3 through 11 (34). The decay scheme used in selecting the gating gamma-ray transitions and in deter mining percent beta feeding to the various daughter energy levels was determined by R. L. Bunting (3S).…”

Nucl. Data A9, 119 (1971). 'With the theoretical value (assumed exact) aT --0.1565 for the 158.6y, we would obtain nT(156.0y) = 46.28 + 0.14. (1971)."Hager and Seltzer employed a (2/3) value. The "correct" value probably lies between these extremes. See A. Rosen and I. Lindgren, Phys. Rev. 176, 114 (1968). ' We briefly note here that the Silv and Band values (based on the Thomas-Fermi-Dirac model) tend to be systematically = l%%uo lower than the Hager and Seltzer values. L. A. Sliv and I.A systematic study of P-decay energies has been made for mass-separated activities of Kr gaseous fission products and their daughters at the TRIsTAN on-line separator facility at the Ames Laboratory research reactor. A well-type plastic scintillator was used in coincidence with a Ge(Li) y detector to determine P-group end-point energies and deduce Q values, The following P-decay energies have been determined: "Kr, 2.93+ 0.03 MeV; "Rb, 5.30+ 0.06 MeV; "Kr, 4.93 + 0.06 MeV; ' Kr, 4.35+ 0.05 MeV; Rb, 6.32+ 0.07 MeV; 'Kr, 6.12+ 0.07 MeV; 'Rb, 5.68+ 0.04 MeV; 'Kr, 5.97 + 0.08 MeV; Rb, 7.58+ 0.15 MeV; Sr, 1.93+ 0.03 MeV; 'Kr, 8.3+ 0.5 MeV; and 'Rb, 7.23+ 0.10 MeV. The decay energies are compared with previous measurements, systematics predictions, and two currently accepted mass relations. The energies are used to predict the P-decay energies for 13 additional nuclei by means of systematics.

“…The y-rays following the decay of 17.8-min 88 Rb and the level scheme of 88 Sr has been well characterised as a result of /3^-decay studies as well as numerous reaction studies of the levels of 88 Sr [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Two of the most recent studies of 88 Rb decay are those of RAGAINI and MEYER [8] and of BUNTING [9], RAGAINI and MEYER [8] in an attempt to resolve the ambiguities existing in the previous works.…”
