Bestimmung der Kernquadrupolmomente der radioaktiven Isotopen Cs135 und Cs137

Abstract: In ha1 tsii bersichtMit Hilfe der Doppelresonanzmethode wurden Hochfrequenziibergange in der Hyperfeinstruktur (im folgenden Hfs) des angeregten 7 2P3,2-Terms des Cs I-Spektrums nachgewiesen l). Die Messungen wurden an einer 0,2 mC-Probe eines Spaltproduktes durchgefiihrt, das die radioaktiven Isotopeii Cs1= und Cs13' sowie das stabile Reinisotop Cs 133 in annahernd gleicher Haufig-8) Die Jenaer Glaswerlre Schot,t 11. Ucn., hkinz, stellten freundlicherweisc allialifcstcs Glas SM 157 zur Verfiigung.

“…The reason for this discrepancy can be found in the value that has been used for g~(1.345) that is very far from both the theoretical (1.3341) and the experimental [1.3340(3), (Abele, 1975a)] values. After this Haroche et al , 1973BaUlnann et al , 1972Kallas et al , 1965Althoff et al , 1954Bucka et al , 1959Svanberg et al , 1969 The symbols have the same meaning as in Table IV. The symbols have the same meaning as in Table IV. correction is applied (using the experimental g~), the A, value of Svanberg and Rydberg (1969) becomes 50.31(4) MHz, and reasonable agreement exists among all measurements. An additional level-crossing experiment has been carried out by Minemoto et aL (1974.…”

“…If instead they used the experimental g= 1.33410(5), their A would be 16.600(7) MHz. For the quadrupole moment Sternheimer and Peierls (1971) have applied a correction factor C = 1/(1 -A) =0.829 to the experimental results of Bucka et al, . (1959), yielding Q = -3.0(11) mb.…”

“…The hyperfine coupling constants of these high Rydberg states can be compared to reported values measured at lower principal quantum number [27,[30][31][32][33][34][35][36][37]. The hyperfine structure results from the Fermi contact interaction of the Rydberg electron with the nucleus and is therefore proportional to the probability density of the Rydberg electron at the nucleus.…”

“…Diese wurden aber zum Beispiel zur Bestimmung der Kopplungskonstanten A und B aus LC-Experimenten an instabilen Cs-Isotopen ben6tigt [1,2]. Deshalb sind, um den gs-Faktor zu ermitteln, am stabilen laacs an den Zust~inden n 2P3/2 (n= 6,7,8,9,10) in letzter Zeit eine Reihe von LC-Untersuchungen durchgeffihrt worden [2,3]: Unter Verwendung der Hfs-Kopplungskonstanten A aus optischen Doppelresonanz-(ODR)-Untersuchungen im Nullfeld [4,5] bzw. aus einem Atomstrahlexperiment [6] konnten somit die jeweiligen gs-Werte ffir n= 6, 7, 8 berechnet werden.…”
