A fre neutron decays into a proton an electron and

Text Solution

Verified by Experts

This statement is false because the neutron is an independent sub atomic particle. It is not formed by the combination of proton and neutron.

A free neutron decays into a proton, an electron and

Assertion: Free Neutron decays into proton, electron and antineutrino Reason : Neutron is unstable outside the nucleus

A neutron initially at rest, decays into a proton, an electron and an antineutrino. The ejected electron has a momentum of 1.4xx10^-26 kg-m/s and that of antineutrino 6.4xx10^-27 kg-m/s. Find the recoil speed of the proton a. if the electron and the antineutrino are ejected along the same direction and b. if they are ejected along perpendicular directions. Mass of the proton 1.67xx10^-27 kg.

Assume that a neutron breaks into a proton and an electron . The energy reased during this process is (mass of neutron = 1.6725 xx 10^(-27) kg mass of proton = 1.6725 xx 10^(-27) kg mass of electron = 9 xx 10^(-31) kg )

A free neutron beta-decays to a proton weth a half-life of 14 minutes .(a)What is the decay constant ?(b)Find the energy liberated in the process.

A free neutron decays spontaneously into

Before the neutrino hypothesis the beta decay process was throught to be the transition. n to p+bar(e) If this was true show that if the neutron was at rest the proton and electron would emerge with fixed energies and calculate them. Experimentally the electron energy was found to have a large range.

A neutron, a proton, an electron and an alpha- particle enter a region of uniform magnetic field with equal velocities. The magnetic field is perpendicular to the paper and directed into it. The tracks of particles are labeled in Fig. 1.132. The neutron follows the track

Which of the following assertions are correct? (i) A neutron can decay to a proton only inside a nucleus (ii) A proton can change to a neutron only inside a nucleus (iii) An isolated neutron can change into a proton (iv) An isolated proton can change into a neutron
