Abstract
We consider decoupled continuous time random walk model with finite
characteristic waiting time and approximate jump length variance. We take the waiting
time probability distribution given by a combination of exponential and Mittag-Leffler
function. Using this waiting time probability distribution we investigate diffusion
behaviors for all the time. We obtain exact solutions for the first two moments
and probability distribution for force-free and linear force cases. Due to the finite
characteristic waiting time and jump length variance the model presents, for the forcefree
case, normal diffusive behavior in the long-time limit. Further, the model can
describe anomalous behavior at the intermediate times.
