## What is diffusion matrix?

Matrix diffusion is the migration of dissolved solutes from flowing macropores or fractures into the more-or-less stagnant pores of adjacent rock matrix.

**How do you find the amount of neutrons?**

To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40−19=21.

**Why only neutron is used for nuclear fission?**

mostly neutrons are used as catalyst in the nuclear reactors. the main point is to exciate heavy ion and make it unstable and it will make fission. in the research, there is a system that we can accelerate heavy ions, and pinch in to light target, like Uranium into to beryllium target. and uranium make fission, again we are just broking the balance inside the nucleus.

### How to calculate and solve for diffusion coefficient?

for the diffusion coefficient in a binary mixture is obtained by Bird, Hirshfelder and Curtiss. Here, Ω = f (kT/ε AB) is the collision integral and k is the Boltzmann’s constant. The interaction parameters ε AB and σ AB determined for the binary system from the appropriate constants for pure substances:

**Is there a Dirac equation for the proton or neutron?**

Dirac’s Equation for the Neutron and Proton Chirgwin, B. H.; Flint, H. T. Abstract. IN the attempt to discover a place for Dirac’s equation in the geometry and metric of the physical world, it has been proposed to make use of Weyl’s concept of gauging. It was thus proposed to bring ubout the union of gravitation and electromagnetism by Kaluza’s

**Is neutron the heaviest fundamental particle?**

The neutron is the heaviest (939.5 MeV). There are many mesons (including the lightest pi, eta and f mesons) with masses between those of the electron and the proton. Most mesons, however, are heavier than the neutron. For details, see the website of the Particle Data Group: Particl
