Product description

Problem 4.5

The mass of a moving electron is three times that of its rest mass. Calculate the de Broglie length

Waves of an electron.

Task 4.15

The kinetic energy of a proton is equal to its rest energy. What is the minimum

Uncertainty of the proton coordinates?

Task 4.25

The particle lies in an infinitely deep one-dimensional potential well of width l in the main

Condition. At which points in the well the probability density of the particle detection coincides with the classical

Probability density.

Task 4.35

Calculate the Rydberg constant and the Bohr radius for the mesic atom - an atom consisting of a proton (the nucleus

Hydrogen atom) and a muon (a particle having the same charge as an electron, and a mass equal to 207

Masses of the electron).

Task 4.45

Calculate the mass defect, binding energy and specific binding energy of the nucleus 23892U.

Task 4.55

Determine the threshold energy for the formation of an electron-positron pair in the Coulomb field

Electron, which occurs according to the scheme

+ E -> e - + e + + e-.

Task 4.65

Each of the ions Na + and Cl- form a face-centered cubic sublattice with the NaCl crystal

Parameter of 0.563 nm. Find the density of sodium chloride.

Task 4.75

Find the amount of heat required to heat 50 g of iron from 10 K to 20 K. The temperature of Debye

For iron is 470 K.
