Abstract
In the neutron deficient isotopes 104,105In lifetimes of high spin states in the
range from 0.5 ps to 600 ps have been measured in a coincidence recoil distance Doppler shift
(RDDS) experiment. By combining the Doppler shift attenuation (DSA) and RDDS methods at few
m flight distances, the problem of delayed feeding has been avoided and very short
lifetimes in the range 0.5 - 0.8 ps have been determined. Shell model calculations with strong
restrictions for the neutron orbitals reveal good agreement with experimental level energies
and still fair agreement for most measured B(M1) and B(E2) values.
