Abstract
An experiment to determine the electromagnetic transition rates in
the yrast sequence of the transitional nucleus, 100 Pd was performed at the
WNSL Nuclear Structure Laboratory, Yale University using the Doppler
Recoil Distance Method in inverse kinematics. A 80 Se beam, accelerated
by the ESTU-1 Tandem Van de Graff Accelerator to 268 MeV impinged
on a stretched, thin 24 Mg foil. The nucleus 100 Pd was produced in this re-
action via the 4n evaporation reaction, with an initial recoil velocity in the
laboratory frame of about 6% the speed of light. The emitted gamma-rays
were measured using the SPEEDY gamma-ray array consisting of eight
compton suppressed germanium clover detectors. The target-stopper dis-
tances were detemined using the New Yale Plunger Device (NYPD). Elec-
tromagnetic transition probability measurements of states of the ground
state band of 100 Pd and the corresponding B(E2) transition strengths are
being determined following the analysis of these data and compared with
the predictions of IBM and Cranked Nilsson-Strutinsky calculations.
