    Notes: Abstract An intrinsic Germanium detector of 10 mm depth and 300 mm2 sensitive area has been used to determineβ-endpoint energies for Rb, Sr and Y fission products. It was calibrated with monoenergetic electrons supplied by a magnetic conversion electron spectrometer for the energy range from 1.6 to 8 MeV. The energy calibration of the detector is linear with deviations less than 2 · 10−4, and the detector was recalibrated daily using precisely known gamma rays of90Rb. At the on-line fission product separator OSTIS at the ILL, Grenoble the endpoints ofβ-singles-spectra have been determined andQ-values deduced if possible also from beta-gamma coincidence measurements. The obtainedQ-values are:88Rb:(5 318±4) keV,89Rb: (4 510 ± 8) keV,90Rb: (6 578 ± 15) keV,91Rb: (5 857 ± 8) keV,91Sr: (2 704.5 ±3) keV,92Rb: (8 111 + 15) keV,93Rb:(7 485 ± 15) keV,94Rb: (10 304 ± 30) keV,94Sr: (3 512 ± 5) keV,94Y: (4 920 ±5)keV,95Rb: (8 947 ±100) keV,95Y: (4 445±5) keV,96Rb: (11 303±250) keV,96Sr: (5 413±20) keV,96Y: (7 120 ±50) keV,97Rb: (10 020 ±50) keV.

    Notes: Abstract An intrinsic germanium detector was used to measure the beta endpoint energies of heavy fission products supplied by the on line mass separator OSTIS installed at the high flux reactor of the Institut Max von Laue-Paul Langevin, Grenoble. The endpoints of singles-spectra have been determined and, by means of beta-gamma coincidence measurements also most of theQ β-values of the following neutron-rich nuclides could be deduced with high accuracy:138Cs: (5388±25)keV,139Cs: (4213±5)keV,139Ba: (2336±25)keV,140Cs: (6220±15)keV,141Cs: (5252+15/-60)keV,141Ba: (3208±35)keV.142Cs: (7329±20)keV,143Cs: (6287+40/-250)keV,143Ba: (4259±40)keV,144Cs: (8451±30)keV,145Cs: (7358±70)keV.146Cs: (9300±900)keV,146Ba: (4280±100)keV.146La: (6175±100)keV. The results are compared with experimental results of direct mass measurements and some predictions by mass formulae.

    Description / Table of Contents: Zusammenfassung Die Lumineszenzspektren der Verbindungen Crha6J3, Crha 6 * J3 (ha* = Deuteroharnstoff), Cr3+∶Mha6J3 und Cr3+∶Mha6(ClO4)3 (M∶Al, Ga) werden bei Stickstofftemperatur und der Temperatur des flüssigen Heliums untersucht. Die Anregung erfolgt über den4 T 2-Zustand. Die Aufspaltung des2 E-Zustandes wird anhand der beiden Null-Null-ÜbergängeE 1/2→4 A 2,E 3/2→4 A 2 (Chrom-Dublett) diskutiert. Aus dem Isotopieeffekt und einem Vergleich mit IR-Messungen können die Begleitbanden als angeregte Schwingungen des Grundzustandes4 A 2 gedeutet werden. Im Mischkristall Cr3+:Gaha6J3 wird eine deutliche Aufspaltung der längerwelligen Chrom-Dublett-Bande beobachtet.
    Notes: Abstract The luminescence spectra of the compounds Cr ur6I3, Cr ur 6 * I3 (ur* = deuterated urea), Cr3+∶M ur6I3 and Cr3+∶M ur6(ClO4)3 (M∶Al; Ga) are studied at temperatures of liquid N2 and He. With the He-Ne-laser as excitation source, the4 T 2-level will be excited. The splitting of the2 E-level will be discussed. It results in two zero-phonon transitionsE 1/2→4A2;E 3/2→4 A 2. From isotope effect and a comparison with IR-data, the side bands can be assigned to the excited vibrations of the ground level4 A 2. In mixed crystalls Cr3+∶Ga ur6I3 an important splitting of the chrom dublett at longer wavelengths would be observed.
