Electric quadrupole moments and strong interaction effects in pionic atoms of /sup 165/Ho, /sup 175/Lu, /sup 176/Lu, /sup 179/Hf and /sup 181/Ta
The effective quadrupole moments Q/sub eff/ of the nuclei of /sup 165/Ho, /sup 175/Lu, /sup 176/Lu, /sup 179/Hf and /sup 181/Ta were accurately measured by detecting the pionic atom 5g-4f x-rays of the elements. The spectroscopic quadrupole moments, Q/sub spec/, were obtained by correcting Q/sub eff/ for nuclear finite size effect, distortion of the pion wave function by the pion-nucleus strong interaction, and contribution to the energy level splittings by the strong interaction. The intrinsic quadrupole moments, Q/sub 0/, were obtained by projecting Q/sub spec/ into the frame of reference fixed on the nucleus. The shift, epsilon/sub 0/, and broadening, GAMMA/sub 0/, of the 4f energy level for all the elements were also measured. Theoretical values of epsilon/sub 0/ and GAMMA/sub 0/ were calculated and compared to the experimental values. The measured values of Q/sub 0/ were compared with existing results in muonic and pionic atoms. The measured values of epsilon/sub 0/ and GAMMA/sub 0/ were also compared with existing values.
