โœฆ Synopsis

We examine the regularized zero-range model in an application to three-fermion systems -the triton and the hypertriton. We consider bound states and low-energy neutron-deuteron and lambdadeuteron scattering. The model is shown to provide an adequate quantitative description of these system on a par with finite-range potential models. The well-known correlation between the doublet nd scattering length and the triton binding energy (Phillips line) finds a natural explanation within the model.

In this paper we use a zero-range potential (ZRP) method to model positron interaction with molecules. This allows us to investigate the effect of molecular vibrations on positron-molecule annihilation using the van der Waals dimer Kr 2 as an example. We also use the ZRP to explore positron binding

In this article, the homotopy perturbation method (HPM) is used to implement the modified regularized long-wave (MRLW) equation with some initial conditions. The method is very efficient and convenient and can be applied to a large class of problems. In the last, three invariants of the motion are e
