Summary
The 2p-1s, 3d-2p, 3p-2s, 2s-2p, 3p-1s and 3d-1s muonic X-ray transitions in208Pb have been used to determine the parameters of a spherical Fermi charge distribution and to deduce the nuclear polarization of the 1s, 2s and 2p muonic levels. We find the fitted value for the 1s nuclear polarization to be larger by a factor of two than calculations; this may shed light on low-lying nuclear compressive modes.
Riassunto
Si sono usate le transizioni muoniche di raggi X 2p-1s, 3d-2p, 3p-2s, 2s-2p, 3p-1s e 3d-1s nel208Pb per determinare i parametri di una distribuzione di carica sferica di Fermi e per dedurre la polarizzazione nucleare dei livelli muonici 1s, 2s e 2p. Si trova che il valore approssimato per la polarizzazione nucleare di 1s è maggiore di quella calcolata per un fattore di due, il che può gettare luce su modi compressivi nucleari inferiori.
Резюме
Используются 2p-1s, 3d-2p, 3p-2s, 2s-2p, 3p-1s и 3d-1s мюонные рентгеновские переходы в208Pb для определения параметров сферического фермираспределения заряда и для получения ядерной поляризации 1s, 2s и 2p мюонных уровней. Мы находим, что эмпирически подобранное значение для 1s ядерной поляризации оказывается в два раза больше, чем вычисления, которые могут пролить свет на низколежащие ядерные сжимающие моды.
