E. Galindo et al., Lifetime measurements of high-spin states in Ag-101 and their interpretation in the interacting boson fermion plus broken pair model - art. no. 034304, PHYS REV C, 6403(3), 2001, pp. 4304
Lifetimes of some 20 high-spin states in Ag-101 in the range between 0.2 an
d 200 ps have been measured using various Doppler shift techniques, The sta
tes have been populated in the reaction Ni-58(Cr-50,alpha 3p) at 200-205 Me
V beam energy and their decays observed by means of the GASP array. For man
y states, the problem of their unknown side-feeding times has been circumve
nted by using the DDCM and NGTB gamma gamma -coincidence methods. A total o
f some 60 reduced transition strengths or limits of them has been deduced.
Moderately enhanced electric quadrupole transitions (up to 30 W.u.) have be
en derived as well as rather strong stretched magnetic dipole transitions w
ithin the negative parity yrast sequence (0.2-0.7) W.u. An attempt has been
made to interpret the level energies and electromagnetic transitions withi
n the interacting boson fermion plus broken pair model.
